[Sir] Henry Fowler
written an extensive, but not authorative, biography of Fowler which concentrates
excessively on his many, and varied, external activities, rather than on
his great contribution as an engineer: partly because the Author has clearly
failed to read what Sir Henry wrote and spoke about.
Michael Rutherford's The era of Sir Henry Fowler. (Railway Refections [No. 33]). Backtrack, 1997, 11, 501-9. examined Fowler in the usual Rutherford style. Several sources are listed which fall outside the period covered by Jones, notably an appreciation by Baldwin, and an important paper by James Clayton. On the other hand it was written prior to Chacksfield's biography. "Direction in new design, if it came, was more by accident and lack of interference than by purpose. It certainly didn't come from Fowler. The Garratts (Anderson's variant) were an example of where the CME should have put his foot down..." The illustrations include Sir Henry Fowler in Scout uniform with Dr H.H.Bemrose Scout commissioner for Derbyshire at the naming of Boy Scout. There is a remarakable comment by Sir Henry on "the disgraceful state" of the nation's roads whether for cyclists or for light motor cars in his contribution to Robson's paper on steam lorries.

A discussion meeting chaired by Sir Henry Fowler. Concluding, Sir Henry welcomed the pertinent points raised by Dr. Kapp. There were many points with regard to the criticism of steam and electric locomotives which might be dealt with if there was time, but the consideration they wanted to lay hold upon was whether it was going to pay to electrify our main lines. There was no insuperable electrical or mechanical difficulty in the electrification of main lines, but there was a difficulty in regard to the financial side of the problem when they were dealing with a low density of traffic. He would again quote his friend, Mr. A.W. Gibbs, who said the difficulties were more mechanical than electrical. The electrical side of the problem seemed to be perfectly sound. There were certain mechanical difficulties. One of them, unfortunately, had not been touched upon, that was the question of low centre of gravity and wheel arrangement.

Two themes were intertwined: the significance of George Stephenson and the significance of metallurgy on mechanical engineering. "I have always been impressed by the fact that George Stephenson seemed to be not only conversant with, but an expert on all that was known and of interest concerning mechanical engineering in his day." "In 1848, Dr Pole translated, from the German, Alban's book on a high pressure boiler, which was in fact an interesting water-tube boiler" (running at 1000 psi). "I have always been impressed by the fact that George Stephenson seemed to be not only conversant with, but an expert on all that was known and of interest concerning mechanical engineering in his day." Standardizing materials: (steels, brasses, bronzes); steel manufacture, metallography, fatigue, radiology, education and higher pressure boilers. Several quotes from Ecclesiasticus: "They will maintain the fabric of the world; and the handywork of their work in their prayer." Aspinall gave the Vote of Thanks pp 746-7.

Armstrong, J.C. Pulverised fuel locomotives.
J. Instn Loco. Engrs., 1929,
19, 90-2. (Paper No. 239).
Sir Henry opened the discussion with some rather penetrating comments:26 years ago, his then chief, Samuel Johnson, sent him to look at a boiler in London whicli vas fired by pulverised fuel, having in his mind the question of its adaptation for locomotive purposes. There was trouble with this boiler, owing to the fact that thc basic slag, which was formed badly, corroded the firebrick which lay in the furnacethis is a trouble with all boilers using pulverised fuel, although Armstrong has not mentioned it. In one of the boilers which he had seen in Germany using pulverised fuel, very little firebrick was used, but hr believed the difficulty had been met by arranging a very large number of burners vhich gave a short flame. One of the greatest difficulties in introducing powdered fuel in connection with electric light plants has been due to this particular point, even uhen some of the combustion chambers were of very large size. The difficulty experienced with a powdered fuel 1ocomotive used in America was similar and overcome by the use of very short flames.

Sir Henry Fowler (351): leak tests very dependent upon size and shape of hole: had collaborated with Gresley on testing. He also noted that with long trains the dimensions of the pipe were very important. He also refered to Fig. 4 as it shows how essential it is that the vacuum creating apparatus, whatever it is, is at the highest state of efficiency. There is a difficulty getting drivers to understand that there are certain conditions which allow him, if he will take the trouble, to work very much more efficiently in maintaining the vacuum. The figures which are given are particularly interesting with regard to the question of the 15 mm., ejectors. We have had some experience with them, but:feel that with an ordinary train one is running pretty near the margin when using them. A vacuum-fitted wagon is one of the worst offenders as regards leakage, due to the maintenance of the train pipe. On the locomotive side, care need to be taken in the fitting of the pipes on locomotives: he had figures which show the very great variation and losses which one can have even on the locomotive itself, necessitating a very much larger amount work being done by the ejector which creates the vacuur owing to the fact of the poor fitting of the pipes.

Sir Henry (298-301) noted the lack of slipping on Underground trains between Charing Cross and Strand and wondered if this was due to hot wheels: tyres became hot in service. He also made observations on the loads on bearings: 7¼ tons on LER as against 19¼ tons on the GIP. Col. Graham (301-2) noted that the dryness of the Underground system reduced the risk of slipping; he also made observations on bearing pressures and on brakes acting upon wheel flanges.
Robson, P.W. Road transport by steam-vehicles.
Proc. Instn Mech. Engrs.,
1920, 99, Disc.: 662-3.
Sir Henry Fowler (662-3) said that, having been the first observer of a steam-driven lorry which went out on official trial in this country, at which trials he had the pleasure of meeting a prominent Member of the Council, he could not help looking back and seeing the great developments which had taken place in these vehicles since that time. He had been particularly interested in what the Author had said with regard to electric vehicles, because he represented a firm which had, he believed, the largest fleet of this type of motors in the country, which they found extremely useful for town deliveries. He was sorry the figures which he could put forward, and which had been published quite recently in Motor Transport, could not be compared with those the Author had given, because the latter had evidently been chosen from typical heavy working under good conditions of loading; these conditions were one of the great essentials for getting the best service not only out of steam-vehicles but any type of motor, and one which railway companies had very gwat difficulty in finding. In view of the constant changes in the rates paid for labour at the present time it would add materially to the usefulness of the Paper if the Author would state, in reference to the figures given on page 642, the date to which these figures applied, as this would be of use for future reference.
With regard to the life of vehicles, his firm purchased two motor vans in 1903 which had only just been disposed of, although for a very considerable time they ran for twenty hours out of the twenty-four. They had a few steam-vehicles, one of which had already had a life of sixteen or seventeen years. A tractor built at Lincoln had a life of about ten years and was still working satisfactorily. One point which had not been touched upon, but which was of vital interest from a warehousing standpoint, was the fire risk with steam-vehicles. That subject had received much greater consideration of late years than in earlier times, but it was a factor which militated against the use of steam-vehicles under certain conditions. He was sorry that from a purely railway standpoint he could not discuss the question which the Author had touched upon in the early part of his Paper in the time at present at his disposal. It must be remembered, however, that motor-vehicles at present ran on a permanent waythe roadswhich was practically speaking free. He lived on the side of a main road between two cities about 60 miles apart, and he knew the difficulty he experienced in using a push-bicycle over that road at the present time, and more so with a fairly light car on four wheels. Undoubtedly this question of roads was a subject which must be handled before the motor-vehicle could be satisfactorily dealt with on the lines suggested by the Author, as many of the roads were at present in a disgraceful state. Until a central authority was established, the roads would not be put into a condition in which they could be used for steam or petrol traction to the greatest advantage, and the question naturally arose as to who was to pay for this. He did not wish to discuss the question of the new taxation of vehicles, but he thought it would hardly meet the state of things which the Author laid down as likely to occur in the future.
Wagner, R.P. (Paper No.
Some new developments of the Stephenson boiler. 5-21. Disc.: 21-47. J. Instn Loco. Engrs., 1930, 20, Fowler p. 24
Sir Henry Fowler (24-5): I agree with Mr. Maunsell that the Paper we have heard requires a great deal of discussion and also a great deal of thought. To begin with, in the first part of the Paper reference is made to the question of a corrugated firebox, and no doubt the Author will remember that the Jacob box of the Santa Fé Railroad of America was on the same principle, but for various reasons it has been abandoned. In the box with which Mr Wagner is experimenting, I am rather doubtful whether trouble may not be experienced owing to the "breathing' which must take place in the corrugations. Something will probably also depend upon the class of water used, and I think difficulties may arise with water which gives a hard china-like scale which might crack along the corrugation and lead to subsequent corrosion.
With regard to the interesting proposal of increasing the number of superheater elements in the smoke tubes, I would point out that one railway in England has adopted for many years elements comprised of six small tubes in each superheater flue tube as against the normal arrangement. On the old Midland Railway, we have tested an engine so fitted, but it did not meet with the success we had hoped.
Coming to the main point of the Paper, which refers to the proportions of the tubes, one can compare the suggestion of Mr. Wagner of area of free space to area of surface of tube with that of Mr. Lawford Fry, who has, as is well known, done such a great work on the proportions of the ordinary boiler tubes, and who advocates that the ratio between the diameter of a tube and its length should not exceed 1 to 100, and it is interesting to note that in the case of a plain boiler tube, if the ratio A /S is 1 /400, as recommended by Mr. Wagner, this is identical with Mr. Lawford Fry's proposed maximum ratio mentioned above.
I would like to know how the figures on Fig. 9 were obtained, because they are of very considerable interest. It is also interesting to see the efficiencies which Mr. \Vagner has given, for after all, one's own children are always much better looking than anyone else's, and I would like to say that on my Company's "Royal Scot" engine, on a run in which we reached l,300 drawbar h.p. and an average speed of about 52 miles, the average boiler thermal efficiency is found to be 80½ per cent.
I have made a tabulated list (see abstract of paper) of boiler proportions which are looked upon as fairly satisfactory and efficient. The manufacturing question comes in with regard to the first three, because they have the same tube plate. We look upon the first boiler; G.7, as probably being the best proportioned one, and it will be seen that the ratios for it vary considerably from those according to Mr. Wagner's proportions.
I have also taken the ratio of internal diameter to length for one of the boilers guoted by Mr. Wagner and I find that this ratio is 1 to 112, somewhat in excess of Mr. Lawford Fry's maximum. I would, however, say that I am not at all in favour of tubes 22 feet in length and of the diameter given.
This is based on A.F. Cook, Radford. Baldwin and Westwood (and in part on Chacksfield). Fowler was born at Evesham, Worcestershire, on 29 July 1870. His father, Henry, dealt in furniture, including antiques. The family were Quakers. The family enjoyed rowing and celebrated Christmas by swimming in the Avon. He was initially educated at the local Grammar School and then attended Mason Science College, Birmingham, between 1885 and 1887 and studied metallurgy under Professor T. Turner. He served an apprenticeship under J.A.F. Aspinall at Horwich from 1887 to 1891. He then spent four years in the Testing Department, working under G. Hughes, whom he succeeded as chief of the department. From 1895 to 1900 he was Gas Engineer of the LYR, transferring to the MR in the same capacity in the latter year.
He was a strict teetotaller, extremely energetic being involved in football, cricket and hockey. He could keep goal or wicket with equal facility. In his spare time he devoted much of his time to the Boy Scout movement, being also keen on cycling and the collection of coins and medals.
Radford: Henry Fowler had joined the Midland Company on June 18, 1900 at a salary of £350 per annum in the position of Gas Engineer & Chief of the Testing Department, from a similar position on the Lancashire and Yorkshire Railway at Horwich. He was to be in just the right place at the right time and reap the full fruits of the clash of personalities soon to develop between Deeley and Paget. Fowler became Assistant Works Manager on November 1, 1905 in succession to Paget. In 1905 he became Assistant Works Manager at Derby, and Works Manager in 1907. In 1907 he was sent to North America to study work management. Two years later he succeeded Deeley as CME. During World War 1 he was seconded to the Ministry of Munitions, being Director of Production from 1915 to 1917 and then Assistant Director General of Aircraft Production. He was knighted in 1918 for his war work.
In 1923 he became Deputy CME of the LMS and Mechanical Engineer, Derby, succeeding Hughes as CME in October 1925. Although notable progress was made in locomotive design under Fowler with the introduction of the Royal Scot 4-6-0, the 2-6-4T and the 0-8-0, he failed to exercise the technical lead and the strict control needed to overcome traditional hostilities and to fuse the CME's department into a unified team. Cox is especially critical of this period.
Fowler had a keen interest in research, particularly in metallurgy. Under his influence the LMS sponsored a major investigation into the behaviour of copper in fireboxes, and he had a reputation for being expert on aspects of boiler materials and design. This interest in research was eventually the means whereby he was removed from the post of CME without openly being down-graded. In 1930 he was given a new post of Assistant to the Vice-President for Works (Research and Development). In this post he pursued his research interests for several years to the Company's benefit, and was responsible for laying the foundations of the LMS Research Depart ment, which in turn formed the basis of the British Railways research organisation. Fowler was also interested in training, and maintained close contact with premium apprentices and pupils for whom he was nominally responsible. C.S. Lake noted that Sir Henry had told him that "he had no enemy but the clock"..
Fowler retired in 1933 and died on 16 October 1938.
Carpenter, George W. biography Oxford Dictionay of National Biography
Hamilton Ellis (The Midland Railway) adds something to the strange relationship between Deeley, Paget and Fowler: On January 1, 1904, Deeley became locomotive superintendent, Paget was made works manager, and Fowler assistant works manager. In spite of their work together, Deeley and Paget were an ill-assorted pair, though both excellent men. To make matters worse, while Deeley was Paget's chief, Paget was a son of Sir Ernest Paget, Bart., chairman of the Midland company, and had wonderful ideas of his own which he intended to put into practice at his earliest convenience. Already people wondered, without speaking, which was really the Sultan and which the Grand Vizier. the background still was Henry Fowler, the Lord in Waiting.
Dow's anecdote is worth adding: At the time corridor tenders for the London-Edinburgh non-stop runs were being considered one of Sir Nigel's daughters found her father one evening on all fours in the family dining-room, squeezing his great bulk through the narrow space formed between a wall and a row of chairs, set side by side. To his daughter's astonished exclamation, 'What on earth are you doing, father?' came the reply, 'If I can get through this, my biggest engineman can' Curiously enough, there was a parallel incident in the career of the late Sir Henry Fowler, the distinguished C.M.E of the old Midland, and of the L.M.S from 1928 to 1931, who was in the habit of cycling round Derby Works to save time. On entering his office one day his assistant, H.G. Ivattson of H.A. and later C.M.E of the L.M.S and now of the London Midland Regiondiscovered Sir Henry on the floor endeavouring to get himself through the round back of his office chair. When Ivatt expressed his surprise Sir Henry explained that he wanted to find out whether or not he could get through a certain type of locomotive firehole which happened to be the same size as the hole in the back of his chair!
Radford tells a similar tale: So far as his employment is concerned, he was extremely particular about boilers and fireboxes, being happy if he could put on a boiler suit and tinker about. He was easily irritated, but this did not last for long, and his usual reply when faced as he was on one occasion by an estimate of six months for a new cylinder pattern was "I want it in three". And that was the end of the discussion. His tours of the Derby Works, while the manager there, were usually made by bicycle, he being easily recognisable in his strawyard hat. He would ride around the Shops inside and out and if he chanced upon someone committing a misdemeanour he would remonstrate with him and then instruct the offender to "clock off" and come back on the morrow, punishment indeed in those days of small wages !
Rudgard (Presidential address Instn Loco. Engrs) stated "On the former Midland Railway, with which I was particularly associated, a tribute is due to the memory of Sir Henry Fowler. His collaboration with Cecil Paget, and their understanding of the running shed angle, helped to produce a school of design which was pre-eminent amongst all the railways forming the London Midland and Scottish in 1923 for reliability and low repair costs, and which, continuing under the LMS, lent itself admirably to the introduction of developments in motive power practice and organisation; Sir William Stanier carried on the good work".
Westwood considered that Henry Fowler was an engineer of all-round ability with (according to Westwood) no great talent in any direction. During his terms of office new designs were built but these could rarely be called his own designs and in some cases were introduced without his genuine approval. As a young man he was involved in the early years of automobile engineering, but ... after he became Chief Mechanical Engineer, Midland locomotive design seemed to stagnate, but this was largely due to the civil engineering department's aversion to larger locomotives; double-heading was preferred to track renewal. Fowler did, however, build his solitary 0-10-0 for banking on the Lickey Incline. After the Railway Amalgamation Fowler became assistant to the chief mechanical engineer of the new LMSR (Hughes) until the latter retired. As chief mechanical engineer in succession to Hughes, he allowed a kind of 'Derby imperialism', foisting Midland practice and design on to the constituent parts of the LMSR. This was resented, and also meant that the Midland 'small engine' policy infected the whole LMSR, Britain's largest railway. However, it was one way of promoting standardization, and Midland locomotives were very robust and cheap in construction and repair. Fowler's proposed 4-6-2 compound, designed to provide the LMSR with a locomotive large enough for its needs, was never built. The superintendent of motive power (J. Anderson) appears to have been the most potent source of opposition to Fowler's proposal; in the end, the LMSR., with scant reference to Fowler, ordered the Royal Scot 4-6-0 from the North British Locomotive Company instead of accepting Fowler's proposed 4-6-2. The introduction of Garratt locomotives also seems to have been more the work of Anderson than of Fowler. Among new designs in the Midland tradition of this period were 2-6-2 and 2-6-4 tank locomotives, the last being the most successful of the Fowler designs. His 0-8-0 was a relative failure, and his proposed 2-8-2 was never built. The peak of Fowler's career was probably 1914-18, when he proved an excellent organizer of munitions production (for which he received a knighthood). See: B. Haresnape, Fowler Locomotives (1972).
From examination of what Sir Henry actually reported it is obvious that Fowler has been grossly maligned by history and by E.S. Cox and Hamilton Ellis (journalist and painter). Certainly, the birth of the LMS was one of the most disastrous corporate events of the twentieth century. In retrospect it was absurd to attempt to merge the LNWR and the Midland Railway. Jenkins (footnotes objects to this statement, but my KPJ view tends to have hardened with the years and should be cast into print) It would have been like bringing the Great Western into common ownership with either of these giants. The LNER worked because the North Eastern was able to retain sufficient status through its contribution to the new company of the brilliant General Manager, Wedgewood, and this enabled Gresley to achieve brilliance. The Southern only worked once it became a greater South Western (the Lord Nelson was a partial failure or success).
A structure which would have tolerated autonomy to remain at both Crewe and Derby might have worked and such a system was briefly contemplated by the LNER. It is probable that both Hughes' and Fowler's reputations might have remained unsullied in such a situation. Unfortunately, the Fowler Pacific was intended for the WCML, and it might have been almost as good as Stanier's earlier attempts: it would certainly have had a less troublesome boiler and left on his own Fowler would have gleaned much from Gresley. The negative contribution of Anderson requires further research
One gets the impression that Fowler was an amiable man with a great interest in people, and although (like Collett) he appears to have been less interested in locomotive design, although more so than has been given credit) he was a considerable engineer with interests in metallurgy, a vital element in locomotive design, and in boilers, and it is tragic that Fury (the high-pressure locomotive should have met with disaster due to metallurgical failure of one of its tubes. The paper on superheating must have been comparable with Gresley's one on high pressure boilers, and this emphasises that Fowler has been badly treated by commentators. His comments on George Stephenson are highly perceptive and contrast sharply with some of the rubbish written by intellectual minnows. Fowler was clearly a brilliant scientific engineer and he must have been extremely well-equipped to assess George Stephenson's extraordinary genius. He must certainly have been a most likeable man: Marjorie Bulleid, Ivatt's daughter, wrote that "The Fowlers were always very kind on Railway Congress meetings".
The following is taken from Cox's Speaking of steam which quotes from Fowler's magnus opus: "From the very dawn of locomotive history the possibility of superheating was being thought about. . . R. Trevethick was the first to apply the system to locomotive engines, and in 1828 he wrote that he was building a small locomotive boiler in which he proposed to heat the steam in small iron tubes as it passed from the boiler to the cylinder. From his patent No 6308 of 1832 it is evident that it was his intention that these tubes should be placed over the fire itself. . . In 1839, Messrs Hawthorn patented a smokebox superheater, while between 1850 and 1870 numerous devices were brought out including examples of practically all the types which have been experimented with in recent years. .. . It seems to have been recognised early that in order to obtain the best results, a fair degree of superheat was necessary, but in practice it was found that this led to trouble both with the valves and the packing. . . . After 1870 use of superheated steam was gradually abandoned and its extensive practical use is a matter of very recent date."
Fowler went on to state that Dr Wilhelm Schmidt began in 1895 to apply to locomotives the knowledge he had gained in the use of superheated steam for other purposes, and in 1897 he produced his first practical design. His previous experience had indicated that the best results were to be looked for in the use of a high degree of superheat, and his successful redevelopment of the process was greatly indebted to the practical trials carried out by Herr Robert Garbe in charge of motive power on the Prussian State Railways. The Schmidt superheater passed through two preliminary design phases before it arrived at the form in which it is known all over the world today. Originally a nest of superheater elements was situated in a vast central tube 1ft 8in diameter connecting firebox to smokebox. Secondly, a superheater entirely within the smokebox was devised, the temperature of the hot gases as they emerged from the small tubes being supplemented by what came out of an additional single large empty tube of 1ft diameter. In both these cases the problem of keeping these large tubes tight in the tubeplates proved insurmountable and the final manifestation was to divide the saturated steam in a header, and pass it down multiple elements placed inside a number of flue tubes of approximately 5in diameter, the steam thus superheated returning to separate compartments in the header, whence it was conveyed by suitable steampipes to the cylindersthe ultimate and basic Schmidt lay out.
This layout proved so wonderfully flexible in permitting by suitable proportions any desired degree of superheat, and relative volume and velocity of hot gases issuing into the smokeboxes and was so simple and cheap and reliable, that in spite of many intermediate variations by engineers who thought they knew better it remained practically unchanged until the last days of steam. Not so was the ancillary gadgetry which was at first thought necessary for its successful use, nor the designs of valves and piston packing which were developed to cope with the high steam temperatures attained. Although many attempts were made, some of them partially successful, to retain slide valves, use of piston valves became general, and since these bore the brunt of the highest temperatures conveyed by the incoming steam, their design was critical. Fowler describes the history of the inception of the Schmidt wide piston valve ring which was for the first two decades and more in almost universal use:

noted that around 1932 Sir Henry Fowler went to America to see the progress made with diesel locomotives there, and on his return decided to carry out what must then have appeared to be large scale experiments. Very satisfactory and encouraqing results were already being obtained with two trial diesel locomotives, the first being the Hunslet 150 h.p. and the second a 250 h.p. Armstrong Whitworth diesel-electric type. Then there were the early Avonside diesel locomotives. Both these locomotives which had previously been on loan were purchased by the LMS and Sir Henry obtained a grant from his board of £30,000 tor experimenting with various types of diesel locomotive. At the time it seemed a tremendous sum and it certainly bought something like ten shunting locomotives, of about the 30-ton mark. It was from these early experiments which lasted several years, that the LMS eventually standardised on the 50-ton 450 h.p. diesel-electric locomotive for shunting purposes, but it has always been his view and still is that the only reason the diesel-electric was selected was because in those early experiments all the diesel-mechanical units were from 150 to 200 h.p. only, while the diesel-electric units were from 250 to 300 h.p. On shunting work and particularly on hump shunting and fly shunting on which all the locomotives were tried, the larger, heavier and more powerful locomotives were obviously bound to be the more useful in moving the traffic. He was quite sure that had it been the other way round and had the diesel-mechanical units been the more powerful and heavier ones, then they would have prevailed just as easily. As it was, the 200 h.p. diesel-mechanical unit was fully proved at that time and ever since has more than justified itself, and it is indeed strange that in the last 25 years the wheel has turned a full circle and British Railways are now using large numbers of 200 h.p. 30-ton diesel-mechanical locomotives.
