Harriet Hall, MD (July 2, 1945 – January 11, 2023) also known as The SkepDoc, was a retired family physician who wrote about pseudoscience and questionable medical practices. She received her BA and MD from the University of Washington, did her internship in the Air Force (the second female ever to do so), and was the first female graduate of the Air Force family practice residency at Eglin Air Force Base. During a long career as an Air Force physician, she held various positions from flight surgeon to DBMS (Director of Base Medical Services) and did everything from delivering babies to taking the controls of a B-52. She retired with the rank of Colonel, then started a second career in science communication, a professional skeptic. In 2008 she published her autobiography, Women Aren’t Supposed to Fly: The Memoirs of a Female Flight Surgeon. A co-founder of the blog, she passed away suddenly in the evening of January 11, 2023, after several years of declining health.
