Dr. Ronald J. Glasser, an Army physician who wrote the acclaimed book, 365 Days, a scorching account of the war in Vietnam through the words of the soldiers who were wounded there, died on Aug. 26 in. St. Louis Park, MN. He was 83.

Dr. Glasser was opposed to the war when he was drafted in August 1968. He was assigned to a hospital in Zama, Japan, one of four frenetic Army hospitals in Japan that every month were receiving 6,000 to 8,000 injured troops airlifted from the battlefields of Vietnam during their 365-day tours of duty.

Dr. Glasser explained in 365 Days, published in 1971, that he had never intended to become a writer, but that he felt compelled to record what he had seen and heard at the hospital.

Reviewing 365 Days, in the New York Times, Thomas Lask said its “quiet eloquence, its factual precision, its emotional restraint braided into the horror and pain of the subject matter make it a book of great emotional impact.”

Dr. Glasser went on to write several other books, including Ward 402 (1973), The Body is the Hero (1976), Another War Another Peace (1985), and Broken Bodies, Shattered Minds (2011).
