Ellen Corby
Ellen Hansen Corby was an American actress. She is most widely remembered for the role of Grandma Esther Walton on the CBS television series The Waltons, for which she won three Emmy Awards. She was also nominated for an Academy Award for her performance as Aunt Trina in I Remember Mama.
Ellen Hansen was born in Racine, Wisconsin, to immigrant parents from Denmark. She grew up in Philadelphia. An interest in amateur theater while in high school led her to Atlantic City in 1932, where she briefly worked as a chorus girl. She moved to Hollywood that same year and got a job as a script girl at RKO Studios and Hal Roach Studios, where she often worked on Our Gang comedies, alongside her future husband, cinematographer Francis Corby. She held that position for the next twelve years and took acting lessons on the side.
