Career
Born in 1920 into a family of four in Los Angeles, California, Ahern got her acting career started in 1923 in the silent film The Call of the Wild, produced by Hal Roach. She went on appearing in many Our Gang films under the Hal Roach Studio, including Cradle Robbers, and is, as of 2015, one of the last surviving Our Gang members. In 1927 another studio, Universal Studios, was in the process of making Uncle Tom"s Cabin.
Not satisfied with the boys who auditioned for the role as Little Harry, Lassie Lou Ahern was contacted and requested to take the part.
Despite this, her career as a child actress ended the same year, with Little Mickey Grogan being her last silent film and her only movie to feature her in a starring role (alongside Frankie Darro). The duo was billed as The Ahern Sisters and mostly appeared in nightclubs and hotels.
She later went on to work as a dance teacher at the Ashram Health Spa, with many known stars as students. During the 1970s, she made several guest appearances in television shows such as The Odd Couple.
