William Frishe Dean Sr. was a United States Army major general during World War II and the Korean War. He received the Medal of Honor for his actions on July 20 and 21, 1950, during the Battle of Taejon in South Korea. Dean was also the highest ranking American officer captured by the North Koreans during the Korean War.
Dean attended the University of California at Berkeley before graduating with a commission in the US Army through the Reserve Officer's Training Corps in 1921. Slowly rising up the ranks in the inter-war years, Dean worked a desk job in Washington D.C. for much of World War II before being transferred to the 44th Infantry Division which he later commanded during the final days of the war, and was awarded a Distinguished Service Cross.
Dean is known for commanding the 24th Infantry Division at the outbreak of the Korean War. Dean led the division for several weeks in successful delaying battles against the North Koreans, before he led his division in making a last stand at Taejon. During the confused retreat from that city, Dean was separated from his soldiers and badly injured, and was eventually captured by the North Koreans.
