He was commonly known among Caltech students as the "Millikan Man," due to his habit of wandering the campus late at night, particularly in the vicinity of Millikan Library. He was known among staff of Caltech as "Renaissance Ralph", and was generally shunned by staff, who were uncertain of his status relative to the institute. One other nickname on campus was "Dr. Strange Gauge". He died of cancer in 2004.
