Executive Committee of the Division of Engineering, the Committee on Undersea Warfare and its Shipbuilding Study Group of the Division of Physical Sciences, the Special Committee on Long-Range Planning of the Highway Research Board, and the Advisory Committee for Study of Non-Rail Transit Vehicles of the Division of Engineering. After his retirement he remained active especially as chairman of the Committee on Undersea Warfare.
Past chairman of the Directors of Industrial Research, Larry also served as a trustee of the Johns Hopkins University, the Carnegie Endowment for International Peace, the MITRE Corporation, and the National Security and Industrial Association. He also served on the Board of Visitors of Tulane University, as chairman of the U.S. Naval Postgraduate School Visiting Committee, and as chairman of the Visiting Committee for Physical Sciences at Johns Hopkins. Larry received honorary awards from his alma mater, the University of Minnesota, the University of Michigan, and Stevens Institute of Technology.
Larry was an early disciple of a systems approach to technical development. He brought much of his enthusiasm for this to General Motors. The range of his eclectic interests continued during the three phases of his career. His thoughtful yet incisive analyses of programs permitted him to contribute to their progress, irrespective of the technical area. A quiet and somewhat reserved mien hid his ongoing interest in the education and development of young scientists and engineers.
Upon retirement Larry and his wife, Mary, and son, Bill, moved from Michigan to the countryside near Chester, Maryland, where they built a new retirement home. Mary predeceased Larry, and he spent his final years living with his son and his son's family in Oldwick, New Jersey.
