The Aldrich Family, a popular radio teenage situation comedy (1939-1953), debuted
on NBC-TV while continuing to air on the radio with a primarily different cast. Over the course of its nearly four-year run on television, Henry was portrayed by five different actors: Robert Casey, Richard Tyler, Henry Girard, Kenneth Nelson and Bobby Ellis,
the only one to participate in the radio production as well. Other characters, including Mrs. Aldrich, Henry’s sister Mary, and his best friend Homer Brown were portrayed by
multiple actors as well, a practice not uncommon in radio but unusual for television, where cast changes are more noticeable.
