Bernard Williams has died. I haven't yet seen links for a memorial but will post them as soon as they are available. Here is a brief biography for Williams from the philosophy department at UC-Berkeley:

Professor Williams received the M.A. degree from Oxford University. After serving in the Royal Air Force, he held a series of academic positions in England. In 1967 has was appointed Knightbridge Professor of Philosophy at Cambridge University, and in 1979, Provost of King's College. He came to Berkeley in 1988; from 1990 to 1996 he also held the position of White's Professor of Moral Philosophy at Oxford University. Professor Williams divides his time between Berkeley and England.

He has been Fellow of the British Academy since 1971 and Foreign Honorable Member of the American Academy of Arts and Sciences since 1983. He has been awarded honorary degrees by the University of Dublin, the University of Aberdeen, Cambridge University, Harvard University, Yale University, and the University of Chicago; he was knighted in 1999.

He has served on several government committees in England, including the Royal Commission on Gambling (1976-78), and he was chairman of the Committee on Obscenity and Film Censorhip (1977-79). He was a member of the Labour Party's Commission on Social Justice (1992-94) and participated in the Independent Inquiry into the Misuse of Drugs Act (1997-2000). From 1967 through 1986 he was a member of the Board of Sadler's Wells Opera (later the English National Opera).

The photographer Sijmen Hendriks has a portrait of Williams here, and, in 1993, David Lavine drew one of those classic caricatures for Williams in the New York Review of Books. Around the publication of Truth and Truthfulness, Stuart Jeffries published a nice profile of Williams in the Guardian. It's available here.

Update: for some tributes to Williams among bloggers, see Bertram, Runnacles, Solum, and Levy. There's now an obituary in the Guardian (noted by Bertram).
