William A. Nolen

William A. Nolen, M.D. (March 20, 1928 - December 20, 1986), was a retired surgeon and author who resided in Litchfield, Minnesota. He wrote a syndicated medical advice column that appeared in McCall's magazine for many years, and was the author of several books. He died on December 20, 1986, at the University of Minnesota Medical Center from heart disease.

His best known book is The Making of a Surgeon, which continues to be a popular (though now dated) narrative about his experiences as an intern and resident surgeon-in-training at Bellevue Hospital in New York City. Many students contemplating medical school find that it guides their decision.

He also wrote Surgeon Under the Knife and eight other books.
