Ronald J. Mario ’65 died on July 20 in Arlington, Virginia. He came to Dartmouth from Keene, New Hampshire, and was an economics major. He began his career at the Prudential Insurance Co. of America in Boston. Executive positions followed at Continental Forest Industries in Stamford, Connecticut, where he spent more than 15 years. In 1985 Ron became the president of Comsat Mobile Communications, a division of Comsat Corp. in Washington, D.C. He also served as chairman of the Inmarsat governing council in London, England, and was a member of the board of directors of ICO Global Communications Ltd. He was proud of his work to improve and save lives around the world through maritime satellite communications. After his retirement in the mid-1990s Ron spent one year as CEO for Spotcast Communications Inc. in Bethesda, Maryland, and established his beloved harness horse racing and breeding business, which he ran successfully for two decades. Ron was a good and generous man of great integrity and humor. He loved Cape May, New Jersey, and Longboat Key, Florida; London and Paris; pizza, coffee milkshakes, and Jack Daniels on the rocks with a twist. He adored his Boston Red Sox, the musical Les Miserables, and driving his vintage gold Mustang convertible. Ron is survived by his wife of 54 years, Helaine; daughter Jessica and husband Brad; son Sean and wife Jenny; and grandchildren Ellie, Tyler, Clare, Declan, and Ian.
