Post The Australian invention of the Black Box flight recorder

The fact that the "Black Box" flight data recorder was invented by an Australian is very well known.

However, this 18th June 2021 story by Allison Marsh writing for the
Institute of Electrical and Electronics Engineers (IEEE) Spectrum Magazine
provides a fascinating read on how David Warren, who was born in 1925
on Groote Eylandt, in the Northern Territory, first floated the idea to
his bosses at the Aeronautical Research Laboratories (ARL), a part
of Australia’s Department of Defence, by way of a Technical Memorandum.

A Melbourne instrument maker made the first prototype in 1958, however :-

The British response was overwhelming, with manufacturers and aircraft operators offering their support.
