the East Germans announced that anyone approaching within 100 meters of the wall would be shot. Jack was directed to challenge this ultimatum. Jack had a rifle squad meet him at Check Point Charlie, the main and most famous of entry points from the U.S. sector into East Berlin. He led this squad on a one mile patrol along and within 10 meters of the wall without incident. This squad received no publicity although they had completed what was, at the time, potentially the most hazardous mission associated with the standoff of the Eastern Bloc and U.S. Forces at the wall. Only a later confrontation of U.S. and Soviet tanks at Check Point Charlie approached the level of potentially explosive hazard of this first mission. In 1962 Jack was assigned to the office of the director of defense research and engineering, in the office of the secretary of defense, where he served until his promotion to brigadier general three years later. In 1965 he was assigned as assistant division commander of the 82nd Airborne Division. Immediately he went to the Dominican Republic to command the 82nd Airborne Task Force, part of the Organization of American States Force sent to quell the revolution there. Upon returning to Fort Bragg, N.C., in late 1965, Jack volunteered for service in Vietnam. He arrived in Vietnam in January 1966, and served successively as the chief of staff and deputy commanding general of the First Field Force, assistant division commander of the First Infantry Division, and commanding general of the 173d Airborne Brigade. He was awarded two Distinguished Service Crosses and two Silver Star Medals, as well as many other lesser awards during this period, and led the only mass parachute assault made during the Vietnam War. Jack returned to the Pentagon from Vietnam in September 1967, with promotion to major general. He served as the director of doctrine, office of the assistant chief of staff, force development and Army representative to the president’s scientific advisory board. During this assignment Jack was directed to prepare a case to convince Secretary of Defense Robert McNamara to reverse his decision which prohibited the Army from developing and fielding an attack helicopter. He developed the concept of formations of attack helicopters, armed with antitank rockets and armor piercing automatic cannons, being the maneuver element of Army Divisions. The concept was met with astonishment by the Army aviation community and with derision and strong opposition by the armored element of the Army. However, it was hailed by Secretary McNamara, in reversing his earlier decision, as the first imaginative thinking he had observed in the Army. After this assignment Jack assumed command of the 82nd Airborne Division in 1968, a position he held for nearly two years. He was then called upon to work directly for the Secretary of Defense as the director of the defense special projects group, which designed and produced various electronic devices used for surveillance of enemy activity. His next assignment, a two-year tour, which brought promotion to lieutenant general, was as deputy director of the defense intelligence agency. From this position he returned to the Army General Staff as deputy chief of staff for research, development and acquisition where he was responsible for planning and budgeting for the Army’s R&D program, and the acquisition of all Army equipment and materiel. His two years in R&D and acquisition led directly to his promotion to general, and assignment as the commanding general of the Army Materiel Command. He was responsible for the execution of the Army’s research and development plans and the procurement of all Army equipment, materiel, supplies and ammunition, and the management of an annual budget in excess of $15 billion. This assignment brought him to the mandatory retirement point of 35 years of service as an officer. Jack served the nation for 40 years – 35 as an officer, four as a West Point Cadet and one as an enlisted soldier. Upon retirement Jack founded a consulting company, which provided advice on the development of technologies aimed at the weapons requirements of the Armed Forces. In 1986 he married his beloved wife, Carolyn, and together they built homes on Seabrook Island, near Charleston, S.C., and on the coast in Gouldsboro. Jack served on the boards of directors of several companies listed on the New York Stock Exchange, one on Nasdaq and several that were privately owned. He continued this work and his consulting until his final retirement to his home on the coast of Maine in 1995.

Kreitler Jr. of Edwards, Colo., and North Palm Beach, Fla., “Margie” Mrs. William R. Gray of Durango, Colo., “BC” Christopher R. Deane of Glendale, Ariz., “Lisa” Ms. Elizabeth H.
