Leonard Huntress Dyer (1873–1955) was an American inventor, patent attorney, and yachtsman from Washington, D.C.
Dyer filed for at least 30 U.S. patents on his own inventions from 1896 to 1934. The most remarkable of his inventions was a patented six-stroke engine using water injected as a 5th stroke for extra power and cooling, to be ejected on the final (sixth) exhaust stroke. It came up in 2008 with regards to the novelty and priority of the Crower six stroke engine.
