Clifford A. Truesdell IV died unexpectedly on March 9,2010 at his home in Cambridge, MA. He was 66 years old. Mr. Truesdell graduated with honors from Harvard College, Brandeis University, and Northeastern University School of Law. His childhood was spent in a number of different states and abroad in Germany, France, and England, but for the past 46 years, he was a devoted resident of Cambridge. Although he was also known for his extensive library and for the range and depth of his many interests including literature, Renaissance art, early music, and classical languages, history and civic engagement were his two main passions. Mr. Truesdell served as the campaign manager for Barbara Ackermann�s 1978 historic bid for Massachusetts governor, and ran two ballot initiatives, one against nuclear power and the other, the first ballot initiative in the country, against U.S. involvement in El Salvador. Truesdell then engineered Peter Vellucci�s successful state representative campaign and served as Vellucci�s trusted aide. Mr. Truesdell was passionate about politics, Cambridge, and his neighborhood, Area Four. In addition to serving as Chair of the Cambridge Democratic City Committee, he was very engaged in efforts to strengthen his neighborhood, primarily through involvement in local community groups and the authoring of a number of downzoning petitions. Mr. Truesdell was a man of unique wit and one who, over the years, played a key role in the lives of his close friends and his two sons. He also enjoyed gardening and hiking in the Green Mountains. Mr. Truesdell is survived by two beloved sons, Cliff of San Francisco, CA, and Samuel of Cambridge, MA. He was married twice, first to Marilyn Richardson and then to Rose Hanig, who also survive him and, though divorced from Clifford, still remained close to him. Donations may be made in his memory to Cambridge Community Foundation (www.cambridgecf.org/giving) or the Appalachian Mountain Club (www.outdoors.org/donations). Friends are cordially invited to a memorial gathering to celebrate Mr. Truesdell�s life on Sunday, March 21 from 2:00-5:00 p.m. in Cambridge at the Middle East, Downstairs (476 Massachusetts Ave., entrance around the corner on Brookline Ave.).
