E.P. Frost lived at West Wratting Hall in Cambridgeshire and became a Justice of the Peace.[1]

Frost began studying flight in 1868 and built a large steam-powered flying machine with both fixed and flapping wings from 1870 to 1877. Frost had intended to have a 20-25 hp steam engine but the actual engine with 5 hp was not powerful enough to lift the ornithopter from the ground. The experiment cost Frost £1000. In collaboration with several colleagues he started another large similar craft in 1902 with an internal combustion engine. It lifted from the ground in 1904.[1] A wing from this craft is displayed in London's Science Museum.
