Theodore Tuttle Woodruff

Theodore Tuttle Woodruff (8 April 1811 - 3 May 1892) was an American inventor. On 2 December 1856, Woodruff received two patents for a convertible car seat, which led to his invention of the sleeping car for railroads. He also helped to manage the Pennsylvania Railroad through its general manager Andrew Carnegie.

Woodruff also invented a coffee-hulling machine, a surveyor's compass and a steam plow.

One of Woodruff's descendants was the 20th century diplomat, Charles Woodruff Yost.
