The Story of the Historical Marker Honoring the McAllister Family Ophthalmic Legacy

Abstract

On August 21, 2022, more than 100 individuals from at least nine different states gathered at Wills Eye Hospital in Philadelphia. Each of the three major eye care professions in the United States was amply represented. The occasion was to celebrate the contributions of John McAllister, Sr. and his descendants, whose early efforts led to the advancement of scientific knowledge, and to the evolution of eye care in the United States. John McAllister is widely regarded as the father (or grandfather) of optometry, since his work and the work of his progeny led to the beginning of optometry as an independent profession. The highlight of the event was the dedication of a historical marker honoring the ophthalmic legacy of the McAllister Family. The marker is situated in Old Town Philadelphia, very near where John’s original optical shoppe was located. The three eye care professions—opticianry, ophthalmology, and optometry—worked hand in hand to make this remarkable achievement possible. This paper tells the story of how and why it all came about.
