Riis, Jacob August

Riis, Jacob August rēs [key], 1849–1914, Danish-American journalist, photographer, and social reformer, b. Denmark. He immigrated to the United States in 1870. In 1877 he became a police reporter for the New York Tribune and later for the New York Evening Sun. His reports on slum dwellings and the abuses of lower-class, largely immigrant life in New York City culminated in his first book, How the Other Half Lives (1890), a groundbreaking work of photojournalism, and earned him the admiration and friendship of Theodore Roosevelt. Riis founded a pioneer settlement house in New York (named for him in 1901). His association with the public park and playground movements was commemorated by the Jacob Riis Park on Long Island.
