NEW YORK - Actress Joan Alexander, who was the voice of Lois Lane in the 1940s radio "Superman" and in an animated television version in the 1960s, died May 21. She was 94.

Alexander died at New York Presbyterian Hospital from an intestinal ailment, according to her daughter, the novelist Jane Stanton Hitchcock.

A native of St. Paul, Minn., Alexander first worked as a model before moving on to radio serials. She played the loyal secretary Della Street in "Perry Mason," then characters on radio soap operas and dramas.

But her most famous role was as Lois Lane, the Daily Planet reporter constantly rescued by Superman. Alexander did voice-overs in animated Superman shorts playing in movie theaters during World War II. She also did the voice in the 1960s for a CBS television Saturday morning cartoon, "The New Adventures of Superman."

Alexander's third husband was Arthur Stanton, an auto distributor who helped introduce the Volkswagen "Beetle" to America. He died in 1987, leaving her $70 million.
