Fritz Langford-Smith (29 June 1904 – 3 December 1966) was an Australian electrical engineer.
He was the author of the classic engineering reference ''Radiotron Designer's Handbook'' (RDH). He was heavily involved in the science of communication and engineering research in England and in Australia. He was a long-term editor of the journal ''Radiotronics'' (1935–1950).
Education and career
Langford-Smith received a Bachelor of Science (BSc) from the
University of Sydney
The University of Sydney (USYD), also known as Sydney University, or informally Sydney Uni, is a public research university located in Sydney, Australia. Founded in 1850, it is the oldest university in Australia and is one of the country's si ...
in 1926. In 1928, he received a Bachelor of Engineering (BE) also from the UoS.
From 1929 to 1932, he was an engineer at Cosmos Lamp Works in the UK. From 1932 to 1956, he worked as an engineer at AWA (
Amalgamated Wireless Australasia) Valve Co. From 1956 to 1963 he was an engineer with the English Electrical Co. in the UK.
From 1935 to 1950 he was editor of ''Radiotronics''.
