John Morgan Clark Jr. (May 28, 1905 – Jan. 30, 1943) was born in Rockwood, Tennessee. He graduated from the University of Tennessee in Liberal Arts in 1924 and then went to attend the University of Tennessee Medical School in Memphis, Tennessee. He was a practicing physician in Tennessee and a reserve officer in the United States Army Medical Corps before the war. He volunteered immediately at the start of the war in 1941 for active duty and was commissioned as a 1st Lieutenant serving the Army’s 44th Station Hospital. The 44th Station Hospital was tasked to follow the 90th Army Engineers in Alaska as they constructed the Unalaska Highway in preparation for a possible Japanese Invasion in 1942. Despite being a medical officer, 1st Lt. Clack endured extreme conditions, grueling terrain, and the Alaskan winter of 1942-1943. It was on January 30th, 1943, that 1st Lt. John M. Clack Jr. suffered a sudden heart attack while working with the 90th Engineers deep in the Alaskan Wilderness. The army attempted to evacuate him to Canada, but he had succumbed to the attack and died before they were able to reach Edmonton, Alberta. He is buried at Oak Grove Cemetery in Rockwood, Tennessee.
