Erik Barnouw (June 23, 1908 – July 19, 2001) was a U.S. historian of radio and television broadcasting.
According to the Scribner Encyclopia of American Lives, Erik Barnouw was born in Den Haag in the Netherlands, the son of Adriaan (a history teacher), and Ann Eliza Barnouw (who tutored English). The Barnouws came to America in 1919, after the end of World War I when his father became one of the editors of the Weekly Review and later was the Queen Wilhelmina Professor at Columbia University. Erik attended Horace Mann School in New York City.
Barnouw, thereafter, went to Princeton University where he was an editor of the Nassau Literary Magazine and collaborated with Joshua Logan on the Princeton Triangle Club's musical play Zuider Zee , after the success of his play Open Collars , which he wrote for Princeton's Theatre Intime and which spoofed undergraduate life at the University. In the spring of his junior year, he and fellow Princetonian Bretaigne Windust, together with Harvard juniors Charles Crane Leatherbee and Kingsley Perry, contributed $100 each towards founding the University Players, a summer stock company in West Falmouth on Cape Cod, Massachusetts. Over the course of 5 summers on Cape Cod and two winter seasons in Baltimore, Maryland, this company gave the professional start to the acting careers of such future stars as Margaret Sullavan, Henry Fonda, Joshua Logan, Myron McCormick, Kent Smith, James Stewart, and Mildred Natwick among others.
Prior to becoming a professor at Columbia University in 1946, Barnouw spent the mid-1930s writing, producing, and directing a number of radio shows for the CBS and NBC radio networks. He also taught Writing for Radio at Columbia on a part-time basis. During World War II he oversaw the Armed Forces Radio Service's education division, based in Washington, D.C. He won a Peabody Award in 1944, for a documentary series, "Words at War." 
Barnouw was elected chairman of the Writers Guild Of America in 1957 and also served on the Board of Governors of the Academy of Television Arts and Sciences.
In 1978 he became chief of the Library of Congress's newly created Motion Picture, Broadcasting and Recorded Sound Division.
He is best known for his history of U.S. radio and television, a three volume series first published in 1966. Volume 1, "A Tower in Babel," covered radio until 1933; the second volume, "'The Golden Web," covered broadcasting until the 1950s; the final volume, "The Image Empire," discussed the rise and growth of television. The New York Times Book Reviews (28 November 1971, p. BR 59) praised Barnouw's work as "continually readable and sharply observant." Barnouw is also known for his history of documentary films, and for his film about Hiroshima and Nagasaki, which the L.A. Times said shook the industry.
In 1971 Barnouw received a George Polk Award.
Barnouw died in Fair Haven, Vermont. The New York Times quoted his former editor Sheldon Mayer, "...Barnouw had an eye for the scoundrels, and the fakes, and the dangerous people. His genius reached generations of Americans across the radio airwaves, on the television screen and in the classroom."
