Roger D. Johnson Jr. ’51

Roger D. Johnson Jr. ’51, Ph.D., a professor of mathematics and an ardent environmentalist, died on April 22 in his hometown of Atlanta. Roger’s early interest in mathematics led him to major in the subject at Dartmouth and to pursue a doctorate at the University of Virginia. He was hired by Georgia Tech immediately after receiving his degree and spent the next 38 years there as a professor of advanced mathematics. He was a lifelong Unitarian and one of the founders of an environmental outdoors group, Ens and Outs, within his church. Ens and Outs collaborated with other environmental organizations to help protect Georgia’s mountains and parks. Roger had a special interest in the state’s water resources, serving as a member of the Georgia Water Coalition. Other environmental groups to which he actively contributed were Earth Ministry and the Northwest Endowment Committee. Friends described him as an “earth champion” and “the mainstay of his church’s earth ministry.” Roger is survived by his wife, Jean, two daughters, three grandchildren and a great-grandchild. His father, Roger, was a member of Dartmouth’s class of 1925.
