David Forbes Martyn FAA FRS (27 June 1906 – 5 March 1970) was a Scottish-born Australian physicist and radiographer.
He contributed to the development of coastal and air defence RADAR for Australia during World War II.
He was awarded the Thomas Ranken Lyle Medal of the Australian National Research Council in 1947 for his discovery of atmospheric tides,[5][6] and received the T. K. Sidey Medal from the Royal Society of New Zealand in the same year, an award set up for outstanding scientific research.
[9] His tours, lectures, diplomacy and encouragement were strongly influential in establishing an effectively communicating Australian scientific community.
[4] He was a keen trout fisherman, which partly explains his growing interests in environmental matters.
