[extract] Like the late Lord Denning, David is not “a very retiring person”. David was born a Jew although he later converted to Anglican Christianity. This has led to a creative tension in his life – British in manner but Jewish in his restless drive and academic entrepreneurship. His drive and output put many of his younger colleagues to shame. He has been involved in 20 books, more than 50 articles and countless papers at seminars and conferences. David in fact counts his joint venture with Mary as his major achievement. David and Mary married in 1980, so their joint venture became in a sense a merger.
