The first board of trustees consisted of five permanent and prominent members of the community; George Meller, Richard Van Valkenburg, John T. Williams, Joseph J. Wharton and John A. Rowe. Erie was unique in the midst of local coal mining towns because the local coal miners actually owned land or houses in town, instead of setting up interim camps.
