Gerald Slater received a Bachelor of Science Degree in Business Administration from New York University. He started his broadcasting career in the commercial end of the field, working for Columbia Broadcasting System from 1960 to 1967. First, from 1960 to 1962, he was a network supervisor, responsible for all operating departments during evenings and weekends as he supervised "on-air" operations for CBS Television Network and WCBS-TV. From 1962 to 1965, as production supervisor, Slater was responsible for production budgets for CBS News. Then, from 1965 to 1967, Slater served as manager of News Production Services. In this job, he created a liaison department between CBS News Division and CBS Television Network to provide central administration of all operations between the two divisions.
Slater's first job in public broadcasting was as director of operations for the Public Broadcasting Laboratory from 1967 to 1969. In this job, he organized all operations of this $15 million experimental weekly television venture funded by a grant from the Ford Foundation to create original drama, arts, and public affairs programming for the first nation-wide public television network. Then, from 1969 to 1970, he worked as a communications specialist for the Ford Foundation. There, as a member of a three person staff responsible for the administration of $18 million in annual television programming grants, Slater initiated, evaluated, and selected program proposals to be funded.
From 1970 to 1975, Slater worked as general manager of the Public Broadcasting Service (PBS) as he was recruited to organize the first U.S. public television network. His responsibilities included establishment of all operating procedures, design of the public network broadcasting land line and satellite distribution systems, as well as setting policies and directing the Programming, Public Information, Business Affairs, Advertising, Station Relations, Operations and Engineering Departments. He negotiated a reduced rate from AT&T for distributing network programs and he set the policy for the relationship between PBS and member stations. In 1973, he was named vice-president of broadcasting at PBS, where his duties included station relations and public information.
From July 1975 to 1989, Slater was executive vice-president of WETA TV/Radio. Here, he managed all operations of public broadcasting stations WETA-TV and WETA-FM in Washington, DC, making final decisions on all programs, and directing 200 employees including producers, executives, on-air talent, engineers, and technicians. He also represented public broadcasting on official visits to Japan and the Soviet Union. Some specific accomplishments Slater did for WETA include the creation of Smithsonian World, a co-production with the Smithsonian Institution and work as Executive in Charge for the station in the creation of the MacNeil/Lehrer News Hour.
From 1989 to the present, Slater has been working for Rock Creek Productions, serving clients such as the American Museum of National History, Corporation for Public Broadcasting, Maryland Public Broadcasting Commission, and the New York City Board of Education. Slater passed away in Washington, DC in April 2020 at the age of 86.
