The Wright Brothers Estate Collection offers a remarkable glimpse into the business and private lives of Wilbur and Orville Wright, inventors of the world’s first successful powered airplane. Descended from the Wright estate, the collection includes original bankbooks, checks, business records, photographs and personal artifacts documenting the brothers’ finances, family relationships and aviation enterprises—from their early years of international fame through Orville’s final decades. Among its highlights are the Wright Brothers’ joint account books, Orville Wright’s personal financial records and material connected with the Wright Cycle Company and their Dayton associates. Together, these objects form an unusually intimate documentary record of two quiet Ohio bicycle mechanics whose ingenuity changed the world.
