Robert M. Evans, a retired computer executive, Air Force veteran and and avid photographer, died Thursday from complications of pneumonia at his home in the Cloisters in the Woodbrook neighborhood of Baltimore County. He was 89. He was the son of Donald Irving Evans Jr., a DuPont Co. draftsman, and his wife, Betty T. Middleton, was born and raised in Pennsauken Township, New Jersey. A scholar-athlete, Mr. Evans was a 1950 graduate of Merchantville High School, and because of his athletic prowess as an outstanding basketball player, he earned an athletic scholarship to the Johns Hopkins University, where he played forward on the university’s basketball team and was the top scorer.
