Robert Edgeworth-Johnstone (4 February 1900 – 3 December 1994) was a British chemical engineer and inventor. Born in Dublin, he spent 33 years in industry as a chemical engineer and consultant, working overseas in the oil industry. A keen musician, Edgeworth-Johnstone developed the Johnstone flute, a simple version of the instrument made from the aluminium brass tubing used in oil refineries. The instrument's design was admired by renowned flautist James Galway, but Edgeworth-Johnstone did little with the invention until he published details in a 1993 book. (From Wikipedia)
