Elizabeth Boger (Betsy Blair), the daughter of an insurance broker, was born in Cliffside Park, New Jersey, on 11th December 1923. After leaving high school she became a model and dancer in New York City.
Betsy Blair married Gene Kelly in 1941. Soon afterwards she won the lead part in The Beautiful People, a play written by William Saroyan. During the Second World War she concentrated on theatre work and bringing up her daughter.
Blair appeared in The Guilt of Janet Ames (1947). This was followed by A Double Life (1947), Another Part of the Forest (1948) and The Snake Pit (1948). She was also active in the Screen Actors Guild and was a strong advocate of setting up an anti-discrimination committee.
In 1947 the House of Un-American Activities Committee (HUAC) began an investigation into the Hollywood Motion Picture Industry. The HUAC interviewed 41 people who were working in Hollywood. These people attended voluntarily and became known as "friendly witnesses". During their interviews they named several people who they accused of holding left-wing views.
One of those named, Bertolt Brecht, an emigrant playwright, gave evidence and then left for East Germany. Ten others: Herbert Biberman, Lester Cole, Albert Maltz, Adrian Scott, Samuel Ornitz, Dalton Trumbo, Edward Dmytryk, Ring Lardner Jr., John Howard Lawson and Alvah Bessie refused to answer any questions.
