My father, Roland L. White, M.D., served in World War II and remained in the Naval Reserves. Like so many other WWII vets, he was recalled to active duty during the Korean War. He had to give up his medical practice, uproot his family (including four children, aged 7 to 2, and report for active duty. He was honorably discharged two years later, in 1954.
I have always believed that his sacrifice cost him not only his probable professional achievements, but his previous close relationships with his friends, peers, and his parents and extended family.
