THE Admiralty has announced that Mr. F. Brundrett has been appointed chief of the Royal Naval Scientific Service in succession to Sir Charles Wright. Mr. Brundrett went to Sidney Sussex College, Cambridge, and obtained first-class honours (Wrangler) in the Mathematical Tripos. During 1916-19 he served in the R.N.V.R., and then was appointed to the scientific staff of H.M. Signal School, where he served in various capacities until 1937, his most outstanding original technical work being on the propagation of short wireless waves and in the organisation of world-wide propagation trials. In 1937 he was transferred to the Scientific Research and Experiment Department, Admiralty, as principal scientific officer, where a sequence of rapid promotions led to his becoming a deputy director of scientific research in 1942. In 1946 Mr. Brundrett was appointed assistant to the chief of the Royal Naval Scientific Service for the reconstruction period.
