[3] Mina Miller Edison played an active role in the social and civic affairs of West Orange, New Jersey, and Fort Myers, Florida, where the family usually resided for several months during the winter.

Yentsch, this is where Mina's influence can be seen concretely: "As her self-identity changed and her influence grew, her imprint on the riverside landscape of the Edison's Fort Myers, Florida, estate changed the grounds from a utilitarian, working space to a graceful, feminine surrounding".
