“During his 26 years at The Times, Champlin served as the paper’s principal film critic from 1967 through 1980. He then shifted to book reviewing and, with his “Critic at Large” column, offered a more general overview of the arts. He retired in 1991 but continued to contribute to The Times’ daily and Sunday Calendar sections and wrote two books despite becoming legally blind from age-related macular degeneration in 1999.”
