Warren Allen Rival completed his life journey on April 18, 2018 at his home in Laconia, New Hampshire, at age 82 with his family by his side. Warren was born in New Britain, Connecticut on March 7, 1936 to Matthias and Loretta (Koerber) Rival. Warren attended New Britain Public Schools until he was fourteen when he went to Williston Academy and then on to Yale University where he continued to use his beautiful baritone voice singing with the Baker’s Dozen and the Yale Glee Club. He was graduated with the class of ’58. Warren started his career in aerospace manufacturing as a manufacturing engineer and factory manager. As an entrepreneur and patent holder he grew his small successful aerospace manufacturing business from three to seventy five employees. The good work of others was always greatly appreciated and respected by him. Whatever recreation Warren allowed himself was for the benefit of his family mainly in the mountains of New Hampshire, Maine, Wyoming and Switzerland, the birthplace of his paternal grandmother. Summer vacations were always on the coast of Maine. In his later years his tennis game became part of the “Old Mens” group. Warren’s quiet intelligence, integrity and industry are carried on by his son Chris and his daughter Mimi who saw their father live his life and endure his long illness with grace. Warren is survived by his wife Jean; his son Christopher (’78) and his wife Suzanne of North Reading, Massachusetts, and his daughter Maria “Mimi” Tlougan and her husband Bruce of Jackson, Wyoming; grandchildren Dr Brook Tlougan and spouse Vijay Karia of New York City and Jackson, Wyoming, and Jay Tlougan and his wife Liza of Jackson, Wyoming; great grandson Rowley Tlougan.
