Roger D. McLeod ’59, also known as Sagamo Powa Matagamon, Chief Sachem of Pawtucket Indian Lodge, died March 21, 2012, in Lowell, Mass. He was born in Rumford on November 9, 1937, and prepared for college at Stephens High School, where he was a member of the National Honor Society and a prize-winning speaker. At Bowdoin, he was vice president of Alpha Tau Omega fraternity, a dean’s list student, and a James Bowdoin Scholar. He began his academic career teaching algebra, physics, and plane geometry at Haverhill (Mass.) High School. In 1962, he was hired as an instructor of physics and graduate mathematics at the Lowell Technological Institute (now University of Massachusetts, Lowell). He was promoted to assistant professor in 1965 and associate professor in 1972. He taught at the school for nearly fifty years. He spent several years studying for his doctorate at Glasgow (Scotland) University. In 1977, he put forth a new theory about vision that he hoped would be developed into a prosthesis that would help the blind to see. Roger was proud of his Native American heritage and worked with several Native American organizations. A deeply spiritual person, he was Chief Sachem of the Pawtucket Indian Lodge and a member of the Merrimack and Greater Lowell Indian Councils. His personal ancestry traced its roots to the Penobscot, Abenaki, Micmac, and Penacook Indian nations, and to the Vikings of the Isle of Skye and Scotland. He was predeceased by his son, David McLeod.
