The story

The EDO Aircraft Corporation began operations on October 16, 1925 in College Point, New York. Although its founder, Earl Dodge Osborne, had dreamed of building airplanes, his first successful product line was EDO floats. Because of a new innovative design, the use of aluminum rather than wood, and the scarcity of hard-surfaced runways in the 1920s, demand built quickly for the floats. With the outbreak of World War II, the company's focus shifted, and EDO began to provide subassemblies for military aircraft of the U.S. Naval Air Corps, U.S. Army Air Forces, and foreign air forces. This shift in emphasis led to the company's being renamed the EDO Corporation in November 1947.

EDO built a factory in 1940 on Long Island, designed by the NYC firm of Malmfeldt, Adams & Prentice. Construction cost was $305,000.
