Frank Morley was a member of Haverford College's Department of Mathematics in the early part of the twentieth century. He is credited with being the first to arrive at the celebrated Morley's trisector theorem:
"The three points of intersection of the adjacent angle trisectors of any triangle form an equilateral triangle."
