Louis Schweitzer (February 5, 1899 – September 20, 1971) was a Russian-born United States paper industrialist and philanthropist who purchased the U.S. radio station WBAI from Theodore Deglin for $34,000 in 1957. An idealist, eccentric, and long-time radio enthusiast, Schweitzer ran the station as a personal hobby and an artistic endeavour, broadcasting the latest in music, politics, and ideas.
Schweitzer viewed radio as an art form, but became increasingly disillusioned with commercial radio as WBAI became more successful. After reading about KPFA and Pacifica Radio in Los Angeles, Schweitzer decided to donate WBAI (which was then valued at around $200,000) to Pacifica, and proceeded to do so in January 1960. WBAI became the third Pacifica station.
Schweitzer's other philanthropic activities included the donation of 1% of his annual income to the United Nations, and the ex gratia purchase of a barber shop on behalf of the barber who had previously rented the premises. Schweitzer's only requirement was an entitlement to a free haircut after regular business hours upon request.
In 1961, he founded the Vera Foundation, later renamed the Vera Institute of Justice, to reduce the numbers of poor people awaiting trial on New York City's Rikers Island. Under Schweitzer's leadership, Vera pioneered the use of controlled, experimental design research methods in state courts. When, in 1966, these experiments convinced the federal government to rewrite the laws governing bail in criminal cases, President Lyndon Johnson credited Schweitzer.
