Roscoe Robinson Jr., 64, the first black four-star U.S. general, died Thursday of leukemia at Walter Reed Army Medical Center in Washington. The St. Louis native was a veteran of the Korean and Vietnam wars. He graduated from the U.S. Military Academy at West Point in 1951 and rose to a number of key military command and staff positions, including commander of the 82nd Airborne Division, culminating in his last assignment as representative to the NATO Military Committee at Mons, Belgium. Shortly after graduation from West Point, he saw action in the Korean War and was again in combat as a battalion commander in Vietnam. His awards and decorations included the Distinguished Service Medal, Silver Star with Oak Leaf Cluster, Legion of Merit with two Oak Leaf clusters, Distinguished Flying Cross and Bronze Star Medal. General Robinson retired from the Army in 1985.
