Career

A leading theoretician, he was the principal inventor of the Roman Club bidding system, from 1956, and with Benito Garozzo after 1969 created Super Precision, a complex strong club based method. He was known as much for his mercurial temperament as for the brilliance of his card play. See, for example, Belladonna coup.

Alan Truscott described him as "a cheerful extrovert" and "normally unflappable at the table".

He had been "a potential soccer star, but World World War II interrupted that career path". He worked in the Social Security Administration until 1970.
