The life and work of Mira Lloyd Dock, the first woman to serve in Pennsylvania state government, provides many insights into the Progressive Era conservation movement and women’s roles within that movement. Dock was heavily involved in the conservation movement at the local, state, and federal levels. Her most ardent supporters said she did more for forests than any woman in the United States. As a member of the Pennsylvania State Forest Commission, Dock helped formulate policies that served as models for other, northeastern industrial states. She also worked tirelessly for women’s rights to have meaningful careers, enroll in institutions of higher education, and vote.
