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 to 1932, he was an engineer at Cosmos Lamp Works in the UK. From 1932 to 1956, he worked as an engineer at AWA. 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.[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] It was also sometimes known as "the big red book" due to its bright-red leatherette cover.[7] It was first published 1934 and revised until 1967.

Honorifics

edit

Honorary member of the Audio Engineering Society in 1959[8] for his Radiotron Designer's Handbook for "its importance in the education of a generation of audio engineers."[9]
