(FOX NEWS) -- Charles Krauthammer, a longtime Fox News contributor, Pulitzer Prize winner, Harvard-trained psychiatrist and best-selling author who came to be known as the dean of conservative commentators, has died. He was 68.

In recent years, Krauthammer was best known for his nightly appearance as a panelist on Fox News' "Special Report with Bret Baier" and as a commentator on various Fox news shows.
