"A man touched with grace, easy to be with and reassuring. In his writings, lectures, and conversation, he never dissembled. His seriousness, manifest in his painstakingly careful speech, was leavened by high humor. The love that people bore him was demonstrated in his hosts of friends—from the teenagers on his Brooklyn block, through the bearded youngsters who came to him for counsel, to the patrician figure of Du Bois, his mentor and his colleague."
