Fritz Langford-Smith (29 June 1904 – 3 December 1966) was an Australian electrical engineer.[1][2][3] He was the author of the classic engineering reference Radiotron Designer's Handbook. 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[edit]

Langford-Smith received a Bachelor of Science (BSc) from the University of Sydney in 1926. In 1928, he received a Bachelor of Engineering (BE) also from the UoS.

From 1929-1932, he was an engineer at Cosmos Lamp Works in the UK. From 1932-1956, he worked as an engineer at AWA (Amalgamated Wireless Australasia) Valve Co. From 1956-1963 he was an engineer with the English Electrical Co. in the UK.

From 1935-1950 he was editor of Radiotronics.[4]

Radiotron Designer's Handbook[edit]

Fritz Langford-Smith was the author of Radiotron Designer's Handbook (or Radio Designer's Handbook) which was often called the "bible" of vacuum tubes and their circuits due to its sheer size and complete scope[5][6] - one edition in the 1940s reportedly was over 2500 pages in length[7] - it was also sometimes known as "the big red book" due to its bright-red leather cover.[8] It was first published 1934 and revised until 1967.

Although long out of print and used copies are rare, editions of the book were scanned and are freely available on the Internet.[9]

Honorifics[edit]

Honorary Member of the Society[which?] in 1959 for his Radiotron Designer's Handbook for "its importance in the education of a generation of audio engineers."[citation needed]
