David B. Guralnik (1921-2000) was a leading lexicographer, Yiddishist, and editor of Webster's dictionaries.
As editor in chief of Webster's New World line of dictionaries from 1948 to 1985, when he retired, he supervised works that carried his view of American English around the world. As a gatekeeper for words seeking admission to the literary mainstream, Mr. Guralnik wrote many of the new definitions himself. He took the title of editor in chief emeritus after he retired, and was a vice president of Simon & Schuster, now the dictionaries' publisher. His name recurred frequently as an arbiter in William Safire's ''On Language'' column in The New York Times Magazine.
