Mary Jane Higby (May 29, 1909 – February 1, 1986)[1] was an American actress in the era of old-time radio and the early years of television.

[10] Higby's signature role was portraying Joan Davis, the female lead on When a Girl Marries, a part she played for 18 years.

[1] Her other roles in radio programs included Cynthia in The Romance of Helen Trent[11] and various supporting parts in Perry Mason[12] Higby was also in the cast of Joe Palooka,[13] John's Other Wife,[13]: 351  Joyce Jordan, Girl Interne,[13]: 357  The Listening Post,[13]: 399  Mary Marlin,[13]: 426  Parties at Pickfair,[13]: 510  Stella Dallas[13]: 662  and This Is Nora Drake.

[15] Higby "had a Hollywood career as a child actress,"[16] primarily acting in silent films for which her father was the director.

A reviewer called the book "a fast, bouncy, information-loaded" description of the era—one that focused on "actors, actresses, sponsors, engineers, agents, writers, sound men, on everything and everybody who made pre-TV radio tick" rather than on herself.
