In celebration of the centenary year of Leonard H. Goldenson’s birth (2006), The Museum of Television and Radio, with the online help of TV Calling, offered this look at the achievements of a great broadcaster and philanthropist. Leonard H. Goldenson helped shape modern mass communications, while his devotion to a range of civic causes—from the promotion of the democratic process to cofounding one of the largest health agencies in the U.S.—left an equally profound legacy.
