After graduating from Harvard Business School in 1951, Gunn started working at Boston's
WGBH-TV. Over the next five years, he had the role of director of operations before assuming the position of general manager in 1957. In 1970 he was chosen as the first president of the Public Broadcasting Service, at least in part due to his "widely acknowledged success in the 1960s at the Boston television station
WGBH". ==Death==
