William Martin Blagden (c1899-1949)
1949 Obituary 
"THE Fighting Vehicle Design Establishment of the Ministry of Supply has suffered a severe loss by the death, on Wednesday, November 30th, in Chertsey Hospital, at the comparatively early age of fifty, of Brigadier William Martin Blagden, its Deputy Chief Engineer.
Brigadier Blagden received his early education at Charterhouse and the Royal Military Academy, Woolwich. In 1919 he was commissioned in the Royal Engineers as a second lieutenant and, in accordance with the normal practice at that time for Royal Engineer officers, he went to Cambridge University to take his degree course. Promotion followed quickly, and in 1931 Captain Blagden was appointed assistant instructor in the School of Military Engineering, a position he continued to hold until 1935, when he became experimental officer in the Mechanisation Experimental Establishment, where he remained until 1939.
He was appointed acting Colonel in October, 1940, and among the positions he held during the 1939- 1945 war we may mention those of Assistant Director of Mechanisation at G.H.Q., B.E.F., and Deputy Director of Armoured Fighting Vehicles, G.H.Q., M.E.F. In 1943 Brigadier Blagden was transferred to the Ministry of Supply and became Deputy Director-General of Fighting Vehicles.
He had an exceptionally wide knowledge of engineering in many of its branches, and it was characteristic of him that he was never at a loss for the meaning of the most obscure technical terms, whether old or new. As an early motor-cycle enthusiast he had a practical and intimate knowledge of road transport. Problems, which he applied with success to the design and operation of fighting vehicles. He had a charm of manner which endeared him to his colleagues and subordinates alike, and his death will be widely mourned by those who knew him. In private life he was a proficient pianist and a musical composer."
