Seabury, Samuel, 1873–1958, American jurist, b. New York City; great-great-grandson of Samuel Seabury (1729–96). He served on the supreme court (1907–14) and on the court of appeals (1914–16) of New York state. He became nationally prominent when he headed (1930–31) investigations of New York City's magistrate courts and the city's politics. As a result of these investigations, Mayor James Walker resigned in 1932. The Tammany faction was defeated in the ensuing elections by Fiorello LaGuardia, whom Seabury had supported. He wrote The New Federalism (1950).
