A Deeper Look at the Gumm Household and What Performing Meant
The domestic life of the Gumm family in Lancaster, California, in the late 1920s and early 1930s was built around performance in a way that makes it difficult to separate what was chosen from what was expected. Frank Gumm ran the Valley Theatre in Lancaster after the family’s move from Minnesota, and the pattern that had been established in Grand Rapids — daughters performing at their father’s theater, mother at the piano, family economics entwined with the economics of entertainment — continued in new geography. The Antelope Valley was not a center of the film industry; Lancaster was a small city at a remove from Hollywood. But it was close enough that the family could participate in audition culture, close enough that the distance between performing at a local theater and performing for a film studio began to seem crossable.
