Charles Herbert Allen (15 April 1848-20 April 1934) was a member of the US House of Representatives (R-MA 8) from 4 March 1885 to 3 March 1889 (succeeding William A. Russell and preceding Frederic T. Greenhalge) and Governor of Puerto Rico from 1 May 1900 to 15 September 1901 (succeeding George Whitefield Davis and preceding William Henry Hunt). Born in Lowell, he ran his family's lumber business before serving in the state house from 1881 to 1882, in the state senate in 1883, in Congress from 1885 to 1889, as Assistant Secretary of the Navy from 1898 to 1900 (taking over from Theodore Roosevelt), and as the first civilian governor of Puerto Rico following the Spanish-American War. Allen was controversial for directing the island's budget surplus towards no-bid contracts for American businessmen, railroad subsidies for sugar plantations, and high salaries for bureaucrats rather than investing in infrastructure or local small business loans. He later worked on Wall Street, becoming president of the American Sugar Refining Company in 1913 and transforming it into what would become Domino Sugar. He died in Lowell in 1934.
