Famous quotes containing the words television and/or work:
“There was a girl who was running the traffic desk, and there was a woman who was on the overnight for radio as a producer, and my desk assistant was a woman. So when the world came to an end, we took over.”
—Marya McLaughlin, U.S. television newswoman. As quoted in Women in Television News, ch. 3, by Judith S. Gelfman (1976)
“...I still have faith occasionally in the brotherhood of man, and in spite of all the tragedies that have intervened since [1945], believe that sometime, somehow, all the nations of the world can work together for the common good.”
—Virginia Crocheron Gildersleeve (1877–1965)
