Frederick Sidney Cotton OBE (17 June 1894 – 13 February 1969) was an Australian inventor, photographer and aviation and photography pioneer, responsible for developing and promoting an early colour film process, and largely responsible for the development of photographic reconnaissance before and during the Second World War. He numbered among his close friends George Eastman, Ian Fleming and Winston Churchill.

Frederick Sidney Cotton was born on 17 June 1894 on a cattle station at Goorganga, near Proserpine, Queensland. He was the third child of Alfred and Annie Cotton, who were involved in pastoralism. Cotton was educated at The Southport School in Queensland and later in 1910, he and his family went to England where he attended Cheltenham College; however the family returned to Australia in 1912. Cotton worked as a jackeroo, training to work with livestock at stations in New South Wales up until the outbreak of war.

Cotton went back to England to join the Royal Naval Air Service in November 1915. After only five hours solo flying, he qualified as a combat pilot, and initially flew Channel patrols. Cotton went on to participate in night bombing sorties over France and Germany with Nos 3 and 5 Wings. His experience with high level and low-temperature flying led Cotton in 1917 to develop the revolutionary new "Sidcot" suit, a flying suit which solved the problem pilots had in keeping warm in the cockpit. This flying suit was widely used by the RAF until the 1950s. Cotton continued with No. 8 Squadron RNAS in 1917 where he was promoted to Flight Sub-Lieutenant in June 1917. Soon after, he came into conflict with senior officers, and resigned his commission in October 1917.

After leaving military service, Cotton married in London a 17-year-old actress, Regmor Agnes Maclean, in October 1917, with whom he had a son. After the war he spent time in Tasmania, then returned to England where he continued his passion for flying. In 1920, he embarked on an unsuccessful attempt to fly from England to South Africa, and also made a lucky escape from a crash at the Aerial Derby. Cotton then spent three years working in Newfoundland flying various assignments.
