In 1966, the Ohio Society of Radiologic Technologists initiated sponsorship of the Guest Invitational Lecture formally called the "Penn-Hu-Mac-Par-Gill Lecture," currently named the Past Presidents Honors Lecture. This lecture series was conceived to pay tribute to members of the OSRT who were elected to serve as President of the ASRT. Currently, there are five (5) members who have served as President of the ASRT. These distinguished technologists are Rubygrant Pennell, R.T.(R): 1954; W. Jay Huston, R.T.(R): 1961; Roland C. McGowan, R.T. (R); Joan Parsons, R.T.(R): 1989 and Julie Gill, R.T.(R): 2014. To be selected as the "Penn-Hu-Mac-Par-Gill" lecturer is one on the highest honors given to an individual by the OSRT.
