History by Contract
History by Contract is a 1978 book by early aviation researchers Major William J. O'Dwyer, U.S. Air Force Reserve (ret.) and Stella Randolph about aviation pioneer Gustave Whitehead. The book focuses on a 1948 agreement between the Smithsonian Institution and the estate of Orville Wright, which stipulates that the Smithsonian, as a condition of owning and displaying the 1903 Wright Flyer, must recognize and label it as the first heavier-than-air machine to make a manned, powered, controlled and sustained flight.
