The DuPont Company developed Cavalcade of America as a dramatic
historical anthology that aired on the radio from 1935 to 1953,
and on television from 1952 to 1957.

Accused of profiteering during World War I by the Nye Committee (officially
the Special Committee on the Investigation of the Munition Industry), DuPont
sponsored the show as a way to rebuild public trust in its brand. Cavalcade
entertained and educated the public with biographical profiles...

Cavalcade proved a success with audiences, and many prominent actors and
writers were associated with the series. Notable actors included Lucille
Ball, Humphrey Bogart, Clark Gable, Gregory Peck, Tyrone Powers, Ronald
Reagan, Edward G. Robinson, Ginger Rogers, Carl Sandburg, Elizabeth Taylor,
Ethel Waters, Orson Welles, and also frequent guests Agnes Moorehead and
Burgess Meredith.

The New York Public Library collection of the Cavalcade of America Radio
scripts, dated from 1935 to 1953, hold almost a complete run of the radio shows.
