Van Doren was dropped by NBC and resigned from his post as an English instructor at Columbia University. He became an editor at Praeger Books and a
pseudonymous (at first) writer, before becoming an editor of the
Encyclopædia Britannica and the author of several books, of which his 1991 popular-market
A History of Knowledge may be his best known. Van Doren also co-authored a well-received revision of
How to Read a Book with its original author, philosopher
Mortimer J. Adler, and co-edited with him a 1,771-page anthology titled
Great Treasury of Western Thought (1977). He had already worked with Adler on an 18-volume collection of documents covering American history, entitled
The Annals of America (1968), which was accompanied by a two-volume, 1,300-page "topical index" organized around 25 themes and entitled
Great Issues in American Life: A Conspectus. In his 2008 article in
The New Yorker, Van Doren revealed that he had actually been contemplating the
Britannica job even at the height of his celebrity. His father had suggested the possibility to him during a long walk around the farmlands they both loved. The elder Van Doren mentioned to his son that Adler, the philosopher and a member of
Britannicas board of editors, had spoken of making Van Doren its editor-in-chief. Van Doren eventually accepted the job, he would write, by way of intercession from a former college roommate. Van Doren retired from
Britannica in 1982. Van Doren also revealed he had been offered an opportunity to participate in a
PBS series on the history of philosophy, but that its tentative producer,
Julian Krainin, might actually have had in mind Van Doren's explicit cooperation on a planned PBS program recalling the quiz show scandals. When that did not occur (though the program thanked Van Doren explicitly, among other credits), he wrote, Krainin later sought his cooperation and consultation when
Robert Redford was beginning to make
Quiz Show—even conveying that Van Doren would be paid in six figures for it. After wrestling with the idea—and, he wrote, noting his wife's objections—Van Doren rejected it. Van Doren finally broke his silence on the quiz show scandal in the
New Yorker article. He revisited Columbia University only twice in the forty years that followed his resignationin 1984 when his son John graduated; and in 1999 at a reunion of Columbia's Class of 1959. During the latter appearance, Van Doren made one allusion to the quiz scandal without mentioning it by name: In 2005, Van Doren joined the faculty of the
University of Connecticut,
Torrington; the campus was closed in 2016. Van Doren spent the last years of his life with his wife, Gerry, in a "small, old house" (his words) on the land his parents bought in
Cornwall, Connecticut, in the 1920s. Van Doren died in a retirement community of natural causes in
Canaan, Connecticut, on April 9, 2019, at age 93. Herb Stempel, the opponent he defeated to win his first game of
Twenty One, died on April 7, 2020, almost exactly one year after Van Doren's death, and at the same age; Stempel's death was not publicly announced until nearly two months later. ==Cultural references==
