The Pawnee was built for Harry Payne Bingham, a financier, sportsman, and philanthropist. Bingham’s father was the president of Standard Tool Co. in Ohio. His maternal grandfather was Henry Payne, U.S. Senator from Ohio between 1885 and 1891, while his paternal grandfather was William Bingham, president of the Cleveland Iron Co. Harry Bingham lived in New York City and was an acquaintance of John D. Rockefeller and Henry Flagler.
Bingham ordered the Pawnee from Pullman for deluxe private transportation between New York City and Palm Beach, Fla. Later, after it was sold by the Bingham family, the car was refurbished by Pullman as Western Union Telegraph Co. No. 100.
