Mr. Rosenthal joined the London office of Messrs. Babcock and Wilcox in 1883 as manager, and with the establishment of the British firm in 1891 he became joint managing director with Mr. Charles A. Knight, the original English representative.
Sir James received the honour of knighthood in 1920 for the services rendered by himself and his firm during the War.
At an early stage of his career he interested himself particularly in the adaptation of the water-tube boiler to marine purposes and in 1896 supplied a set of boilers to the British Navy for the gunboat "Sheldrake," at the time when there was acute discussion on the subject of water-tube boilers for naval service.

He was also a Member of the Institution of Naval Architects and was a Justice of the Peace for the city of Glasgow.
1927 Obituary 
SIR JAMES H. R. KEMNAL, well known throughout the world as managing director of Messrs. Babcock and Wilcox, Ltd., died somewhat suddenly on the 8th February, 1927, in his sixty-third year.
Originally known as Mr. James Rosenthal, he was born in London, of British parents, his father being Mr. James Rosenthal, a naturalized British subject, and his mother of Scottish descent.
He was first educated in London, and later proceeded to Cologne University, afterwards entering the works of the Belgian State Railways as an apprentice.
On completing his apprenticeship he joined the engineering staff of the Anderson Foundry Co., Ltd., and whilst there became acquainted, in 1881, with Mr. Charles A. Knight, who was then establishing a British branch of the Babcock and Wilcox Co. of New York, U.S.A., of which branch Mr. Rosenthal was appointed manager in 1883. The rapid progress made, and the amount of business transacted, were such as to justify the formation in 1891 of a separate British company of which he became managing director, conjointly with Mr. Knight.
Works were established at Renfrew and employment was found for some 130 men.
In 1900 the company was reconstructed, with increased capital, under the title of Babcock and Wilcox, Ltd., with Mr. Rosenthal as managing director.
In 1915 he assumed the name of Kemnal.
Throughout the War his personal energies and the manufacturing resources of the company were practically devoted to meeting national needs, and in 1920 he received the honour of knighthood for the services which he, and the company, had rendered. He also served as president of the British and Latin American Chamber of Commerce, and in all these capacities displayed a master mind and was successful in securing the most loyal and active assistance of all associated with him in his various activities.
In addition to being a member of various technical institutions, he was a Fellow of the Royal Society, Edinburgh, a liveryman of the Worshipful Company of Shipwrights, a Freeman of the City of London, a Justice of the Peace for the City of Glasgow, and, had he lived, the LL.D. Degree would have been bestowed upon him by the Glasgow University. During the past 40 years he was most closely identified with the development of steam-generating plant for electric power stations, the Navy, and the Mercantile Marine, and he contributed valuable papers to several of the Institutions and the first World Power Conference.
He was elected an Associate of the Institution in 1888, and a Member in 1908.
1927 Obituary 
Sir JAMES KEMNAL, J.P., F.R.S.E., managing director of Messrs. Babcock & Wilcox, Ltd., died on February 8, 1927.
Sir James Kemnal was intimately associated with the growth and development of the Babcock Company, which, in the first instance, was a branch of the Babcock & Wilcox Company of New York, on whose behalf Mr. Charles A. Knight came over to England to make the commencement in 1881, and Mr. Knight still remains an active director of the Babcock organization. The progress of the branch, however, justified the institution in 1891 of a British company for the purpose of carrying on the business.
In 1891 Sir James Kemnal became the managing director of the company conjointly with Mr. Knight, and in 1900, owing to the success of the company, an increase in capital became necessary, and Babcock & Wilcox, Ltd., was reconstituted to suit these conditions, with Sir James Kemnal as managing director. Since that date the success of the company has been phenomenal, and the original capital in 1890 of £240,000 is now £4,500,000 and as an indication of the soundness of the manner in which the business was conducted during the recent much-to-be-regretted coal strike this was one of the few engineering companies able to continue operations without suffering severe loss and without material reduction of output.
Sir James Kemnal was one of the pioneers in the development of electrical power, in consequence of the adaptability of the Babcock productions for this particular branch of trade. For services rendered to the nation during the war he received the honour of knighthood in 1920. He was a director of the following: all the foreign Babcock companies Power Securities Corporation Balfour, Beatty & Co., Ltd. Power and. Traction Finance Co. (Poland), Ltd. and Chairman of Messrs. Worthington-Simpson, Ltd. He was also President of the British and Latin American Chamber of Commerce.
He was a member of the Institution of Mechanical Engineers, Institution of Naval Architects, Institution of Electrical Engineers, and other Societies, and also a Fellow of the Royal Society of Edinburgh, and recently was appointed a Justice of the Peace of the City of Glasgow, and if he had lived the honour of LL.D., Glasgow, would have been conferred on him. He was a Liveryman of the Shipwrights Company, and a Freeman of the City of London. Sir James controlled, as management director of the Board, factories at Renfrew, Dumbarton, Oldbury, Lincoln, Sydney (Australia), and Yokohama (Japan), altogether with some 10,000 employees.
In addition, he was a director of most of the subsidiary companies in France, Germany, Spain, Italy, and Canada. In all these activities, he displayed a master mind in securing the assistance of those most loyal and active in the interests of the great concern he was himself able to create. His business capacity, ability, and power of application were well recognized in financial, engineering, and commercial circles. He was unfortunately taken seriously ill in September 1926, and was not able to give full attention to business for the last five months of his life. His death will be mourned by a very large circle of friends and associates.
Sir James Kemnal was elected a Member of the Institute on October 14, 1909.

"THE LATE SIR JAMES KEMNAL.
The death of Sir James Kemnal, which occurred at Sandbanks, Dorset, on Tuesday last, after an illness lasting several months, removes an engineer who was known throughout the world in the sphere of boiler construction. Sir James, who was born in London in 1864, was associated with Messrs. Babcock and Wilcox, Limited, for the greater part of his life, and had occupied the position of managing director of the company for many years. The firm was originally a branch of the Babcock and Wilcox Company of New York, LLS.A., and, on behalf of that company, Mr. C. A. Knight came to England in 1881. The growth of the English branch was so rapid that, ten years later, a British company was formed, and Sir James Kemnal became managing director of the new firm, conjointly with Mr. Knight. The British concern continued to make rapid progress and, in 1900, the company was entirely reconstituted, and Sir James was appointed managing director, a position which he occupied until his death. In this capacity he had control of factories at Renfrew, Dumbarton, Oldbury, Lincoln, Sydney, and Yokohama, the combined personnel of which totals 10,000. Sir James was also a director of the French, Spanish, Italian, and German companies of Messrs. Babcock and Wilcox, of Messrs. Power Securities Corporation, London, of Messrs. Balfour, Beatty and Co., Limited, London, and of other companies. He was also Chairman of Messrs. Worthington-Simpson, Limited, London, and Newark, and President of the British and Latin-America Chamber of Commerce.
Sir James was a member of a large number of technical and scientific institutions. He was elected to the full membership of the Institution of Mechanical Engineers in 1889, of the North East Coast Institution of Engineers and Shipbuilders in 1896, of the Institution of Engineers and Shipbuilders in Scotland in 1896, and of the Institution of Electrical Engineers in 1908. He became a member of the Iron and Steel Institute in 1906, and was one of the original members of the Institute of Metals when that body was founded in 1908. He was also a vice-president of the Institute of Marine Engineers and a member of the Institution of Naval Architects. Among the papers contributed by him to the transactions of various learned societies, the following may be cited : “ Water-tube Boilers in the Mercantile Marine,” read before the North-East Coast Institution of Engineers and Shipbuilders, in January, 1921 ;“ Water-tube Boilers and Crane Construction,” read before the Institution of Mechanical Engineers at Glasgow in June, 1923; “ Present Tendencies of Steam Generation,” read before the Institute of Marine Engineers in October, 1924; and “ High-pressure Boilers,” read before the Institution of Engineers and Shipbuilders in Scotland in February, 1926. Sir James was a Fellow of the Royal Society of Edinburgh and had recently been appointed a magistrate of the City of Glasgow. He was a Freeman of the City of London and a Liveryman of the Shipwrights’ Company. In recognition of services rendered by him during the war he received the honour of knighthood in 1920. Sir James became seriously ill in September last, and had continued to be unwell since that time. The news of his death will be heard with great regret by engineers the world over."
