Pierce Butler (judge)

Pierce Butler (March 17, 1866 – November 16, 1939) was an American jurist who served as an associate justice of the Supreme Court of the United States from 1923 until his death in 1939. He was a staunch conservative and was regarded as a part of the Four Horsemen, the conservative bloc that dominated the Supreme Court during the 1930s. A devout Catholic, he was also the sole dissenter in the later case Buck v. Bell, though he did not write an opinion.
