[Letter to Frederick Eppelsheimer from Orville Wright, April 7, 1915]
Letter to Frederick Eppelsheimer of the New York Herald from Orville Wright, April 7, 1915. Discusses the use of pendulums in providing lateral stabilization for aircraft and the conditions necessary for soaring or hovering flight. Also mentions the death of Wilbur Wright in 1912 and the work of fellow aviation pioneer Glenn Curtiss. Four (4) typed pages.
The letter is accompanied by a small, matte-finish portrait of Eppelsheimer, dated 1918, apparently used for a passport.
