Whitelaw Reid (October 27, 1837 – December 15, 1912) was an American politician and newspaper editor, as well as the author of a popular history of Ohio in the Civil War. After assisting Horace Greeley as editor of the powerful Republican newspaper, the New York Tribune, Reid purchased the paper after Greeley's death in 1872 and controlled it until his own death. The circulation grew to about 60,000 a day, but the weekly edition became less important. He invested heavily in new technology, such as the Hoe printing press and the Linotype machine, but bitterly fought against the unionized workers for control of his shop. As a famous voice of the Republican Party, he was honored with appointments as ambassador to France (1889) and Great Britain (1905), as well as numerous other honorific positions. In 1898 President William McKinley appointed him to the American commission that negotiated peace with Spain after the Spanish-American War.
