Winston Eugene Arnow (March 13, 1911 – November 28, 1994) was an American lawyer and judge of the United States District Court for the Northern District of Florida. He presided over the Gainesville Eight trial.
Arnow was born in Micanopy, Florida, near Gainesville. Arnow received his Bachelor of Business Administration degree from University of Florida in 1932 and his J.D. from the University of Florida College of Law in 1933. He briefly entered private practice in Gainesville from 1933 before taking a statistical position with the Federal Emergency Relief Administration in Florida from 1933 to 1934. Arnow served as a law clerk to the Florida Supreme Court in Tallahassee from 1934 to 1935.
Arnow returned to private practice in Gainesville from 1935 to 1942. From 1940 to 1942 he served as a municipal judge of the City of Gainesville before serving in the United States Army in the Judge Advocate General's Corps as a major from 1942 to 1946, during World War II. Arnow resumed his position as a Gainesville municipal judge from 1946 to 1949 before returning to private practice.
President Lyndon B. Johnson nominated Arnow to the United States District Court for the Northern District of Florida on November 29, 1967, to a new seat created by 80 Stat. 75. Confirmed by the Senate on December 7, 1967, he received commission the same day.
In 1969, Arnow ordered the Escambia County School District desegregated. In 1972 he presided over the trial of the Gainesville Eight anti-Vietnam War activists who were indicted on charges of conspiracy to disrupt the 1972 Republican National Convention in Miami Beach, Florida. All eight were acquitted. In 1978 he drew up a special district to assure that the county commission would have at least one black member. In 1981 he sealed a settlement in a discrimination case, requiring the U.S. Air Force to establish a $2 million fund and Eglin Air Force Base to hire 100 black workers for its civilian labor force and promote others already on the payroll.
Arnow served as chief judge from 1969 to 1981, assuming senior status on March 14, 1981. He remained on the court until he died at West Florida Hospital in Pensacola, Florida in 1994 at age 84 after a long illness. He was married to Frances Day Arnow. The Winston E. Arnow United States Courthouse in Pensacola was renamed in his honor in 2004.
