Career
Seabrook was teamed with comedian Emerson Treacy to form the double-act Treacy and Seabrook. Seabrook also appeared as the ditzy mother of Spanky McFarland in the Our Gang short films Bedtime Worries and Wild Poses. In addition to her work with Treacy, Seabrook sometimes supplied the voice of Sniffles, an early character on the Warner Brothers roster created by Chuck Jones, though several other voice actresses, most notably Marjorie Tarlton and Leone Ledoux, are also credited with doing the voice of Sniffles from time to time.
Seabrook died on April 18, 1970.
