Gertrude "Trudy" Warner was a voice actor in the Golden Age of Radio. Warner was born in Hartford, Connecticut in 1917 and died in New York City in 1986.

By any account, Trudy Warner's career has to stand as one of the ten most ambitious, successful such careers in the history of radio ... some 28 years and well over 4,000 performances. She was considered one of the queens of daytime radio, appearing in dozens of daytime serials. She portrayed such well known characters as "the lovely Margot Lane" on The Shadow and Della Street on the daytime Perry Mason. The Lux Radio Theater episode of Mrs. Miniver proved so popular, it was developed into a daytime serial with Warner in the title role and as narrator. She was the third busiest actor in the Golden Age of Radio.
