Pathe Studios tree planting, 1929- Dorothy Appleby plants a cherry tree on the lawn at Pathe studios after it was presented to the Culver City Chamber of Commerce. Morton MacCormack, chamber secretary, assisted in the planting after he accepted the tree on behalf of the chamber on this cool day in February.
Dorothy Appleby does not seem to have made any movies for Pathe. That studio was having difficulties during the transition period from silent movies to talking pictures and would cease the production of features in 1931, although they continued to distribute newsreels for years afterwards.
