Stella Obst joined the Olmsted Brothers in 1914 after graduating from Wellesley with a degree in History. Although conventions of the period largely precluded women from engaging in design work, Obst soon became an essential asset to the firm. In her capacity as Frederick Law Olmsted, Jr.'s personal secretary, Obst was the only female employee to participate in the cross-country excursion to Palos Verdes. She remained with the Olmsted Brothers until 1960, when she retired at seventy years old. Obst's career, which spanned seven decades, highlights the unacknowledged labor that undergirded the Olmsteds' success.
