  1. Michael. E Fitzgerald, former AOA director of publications

    Thomas Wesley Allen, DO, is best known for his 10.5 years as the American Osteopathic Association’s editor in chief. While holding that position from 1987 to 1998, Dr Allen greatly enhanced the peer-review process for “JAOA–The Journal of the American Osteopathic Association,” which is now the “Journal of Osteopathic Medicine.”

    Among the chief issues he championed as editor in chief was the AOA’s 1960 position statement designating “osteopathic medicine” and “osteopathic physician” to be the profession’s preferred terms in place of “osteopathy” and “osteopath,” respectively. Consequently, during Dr Allen’s tenure as editor, the AOA’s publications were careful to refer to the profession as the “osteopathic medical profession,” not the “osteopathic profession.”

    An an educator, researcher, and politician, Dr Allen accomplished a great deal for osteopathic medicine beyond serving as the AOA’s editor. Here are just a few of his achievements:

    –Dr Allen served on the faculty of three osteopathic medical colleges and one MD college. Most notably, he served as the dean and vice president for academic affairs at the Midwestern University/Chicago College of Osteopathic Medicine and the dean and vice president for health affairs at the Oklahoma State University College of Osteopathic Medicine.

    –He chaired the American Association of Colleges of Osteopathic Medicine’s Council of Deans in 1980.

    —-He was the American College of Osteopathic Internists’ 1986-1987 president.

    Dr. Philip Todaro of Georgia passed away a few months ago. I did not see it in your list of deceased doctors. He was in the class of 71 KCU

  3. Tyler Cymet

    We wouldn’t be osteopathic medicine without Tom W Allen, or TWA as he was known. TWA bridged old school osteopathy and osteopathic medicine with a passion. As the AOA’s first scientific advisor and George Northups quality control reviewer, he enforced the AOA standing on solid scientific ground.
    An internist and pulmonologist who trained at Northwestern University he pursued education and administration Deaning at CCOM, UMDNJ (Rowan), and OSU. He was also the Chair of the AACOM Board of Deans. He edited the JAOA for years paying close attention to the soundness of the articles he published without yielding to “Family pressure” to put relationships over quality.
    During my research fellowship at CCOM, TWA was ready to help any student ‘sharpen their questions” and rethink their thoughts.
    He demanded respect for the profession while pushing the profession to maintain standards that earned respect from ourselves.
    He was a marathoner who enjoyed singing and performing, He was a workaholic who didn’t know how to say no to any request for help or request from the profession to contribute.
    And as editor of the JAOA, he demanded we use the terms osteopathic medicine and not osteopathy.
    The profession owes Dr Allen respect and appreciation for all he did.

    Dr. Allen was a true leader of our profession. He showed us how it’s done, with excellence in every thing he did. An exemplary role model! He will be sorely missed.
