Charles Henry Bennett (b. 1943) is a Physicist, Information theorist and IBM Fellow at IBM Research. Bennett's recent work at IBM has concentrated on a re-examination of the physical basis of information, applying quantum physics to the problems surrounding information exchange. He has played a major role in elucidating the interconnections between physics and information, particularly in the realm of quantum computation, but also in cellular automata and reversible computing. He discovered, with Gilles Brassard, the concept of quantum cryptography and is one of the founding fathers of modern quantum information theory (cf. Bennett's four laws of quantum information).
1.) "I am so sorry to hear of Asher's passing. I will miss his scientific insight and advice, but even more his humor and stuborn integrity. I remember when one of his colleagues complained about Asher's always rejecting his manuscript when they were sent to him to referee. Asher said in effect, "You should thank me. I am only trying to protect your reputation." He often pretended to consult me, a fellow atheist, on matters of religious protocol. As we waited in line to eat the hors d'oeuvres at a conference in Evanston, he said, "There is a prayer Jews traditionally say when they do something new that they have never done before. I am about to eat a new kind of non-Kosher food. Do you think I should say the prayer?" My wife and grown children, who are visiting us this new year, and remember Asher from when we all lived in Cambridge 20 years ago, join me in sending you our condolences for this sudden loss of an irrepressible and irreplaceable person. Please convey our feelings especially to your mother at this difficult time. " H. Bennett Charles H. Bennett's letter written to the family of Israeli physicist, Asher Peres, A selection of the many letters of condolence sent to the Peres family during January 2005.
