Norman Leventhal was born and raised in Boston, Massachusetts. He is a 1933 graduate of Boston Latin School and a 1938 graduate of the Massachusetts Institute of Technology. In 1946 he co-founded Beacon Construction Company, which grew to become an award-winning developer and manager of office buildings, housing and hotels. Mr. Leventhal serves as a life member emeritus of the MIT Corporation. He was the Chairman of the Trust for City Hall Plaza since its inception in 1995 until December 2000. He is a Board member and former Chairman of the Friends of Post Office Square. He is the past Chairman of the Artery Business Committee and presently serves on its Executive Committee. Mr. Leventhal is a board member of the Picower Foundation. The death of his brother Robert in 1972, at 58, was “both a personal tragedy and a professional setback." His son-in-law Ed Sidman died in 2005. Mr. Leventhal’s sister, Dorothy Levinson, died in 2007, and another brother, Edward, died in 2012. Mr. Leventhal married Muriel Guren in 1941 and began each day saying to her, “Good morning, my dear, it’s a beautiful day.” When an MIT alumni publication asked him in 2008 to name his greatest accomplishment, he answered: “Marrying Muriel.” A service will be announced for Mr. Leventhal, who in addition to his wife, of Palm Beach, Fla., and Boston, and his sons Alan of Chestnut Hill and Mark of Waban, leaves a daughter, Paula Sidman of Palm Beach, Fla.; 11 grandchildren; and seven great-grandchildren.
