....For sixty years, he was one of my closest friends. My debt to him, both personal and professional, is beyond measure. Despite deep sadness at his death, I cannot recall him without a smile rising to my lips. He was as quick of wit as of mind. His wit always had a point, and was never mean or nasty — though some of the objects of his wit no doubt felt its sting. His occasional humorous articles — such as “The History of Truth in Teaching” — have become classics and demonstrate that had he chosen to become a professional humorist rather than a professional economist, he would have achieved no less fame in the one field than he did in the other. His death has left the world a far less joyful place for Rose and me, as for so many others.
