TV news pioneer Joseph Wershba, an Emmy-winning CBS News producer and reporter, whose work helped to bring the McCarthy witch hunts to an end, has died at the age of 90.

The Associated Press reports that Wershba, who was one of the original '60 Minutes' producers, died at his home at Long Island, New York of complications from pneumonia.

In a statement, CBS News Chairman Jeff Fager said, "Joe Wershba was a wonderful man who was a pioneer of broadcast journalism, without the notoriety of his more celebrated colleagues Ed Murrow and Don Hewitt. ... Almost everything he touched became part of the foundation for CBS News, including '60 Minutes.'"

In 1954 Wershba led a report on Sen. McCarthy for Edward R. Murrow's CBS TV news segment, 'See It Now.' The exposé helped discredit McCarthy, and was one of the inspirations for the movie 'Good Night and Good Luck,' in which Wershba was played by Robert Downey, Jr.
