Last Thanksgiving Day brought with it sad news: An obituary in The New York Times told of the death of Joseph J. Thorndike, Jr.

His passing severed a final strand connecting American Heritage to its corporate past, for Joe was the last of our three founders. Years ago, he had teamed up with two Life colleagues, Oliver Jensen and James Parton, to form a publishing company of their own. All three men knew plenty about magazines, but Joe’s experience was especially formidable. Born in Peabody, Massachusetts in 1913, he had graduated from Harvard before going to work for Henry Luce. In time, he became managing editor (which in the Luce empire meant “editor in chief”) of Life, then at the peak of its influence. With Jim Parton handling the business side, Joe and Oliver gambled that a magazine combining their Life-honed knowledge of the pictorial with well-written popular history would find an audience. That was more than a half-century ago, and here we still are.

I drew my first American Heritage paycheck in the summer of 1965, when the company generously accepted my efforts as a mailboy. The mid-60s were a great time to be at Heritage, even in so minor a position as mine. It was a big operation then, far larger than it is today, with a half-dozen floors’ worth of different divisions, including (a portent of our future ownership perhaps) a financial newsletter.

David McCullough and his staff were editing a history of World War II that has been in print ever since. Richard Ketchum had not long before overseen the genesis of a Civil War history that won a Pulitzer Prize. (Its text had been written by Bruce Catton, whom I would see in his office, clacking out with newsman’s speed on yellow copy paper paragraph after paragraph so well wrought that the pages would go directly from his Underwood to the press with nary an editorial scratch.) And Joe Thorndike was running Horizon, a still keenly missed magazine that reflected the immense breadth of his interests. Horizon was an American Heritage that covered every nation and every era: An issue might contain a story on the great age of the Dutch Republic and Hadrian’s Wall (which Joe took his young son on a vacation to explore), a comparison of Tennessee Williams’s and Seneca’s ideas of tragedy, and the wonderfully fluent Gilbert Highet making sense of Hieronymus Bosch’s hellscapes.

Nobody knew more about more things than did Joe Thorndike; no one was a more enthusiastic traveler along every intellectual pathway. But the fires of his enthusiasm lay banked, or seemed to, for Joe was a model of New England reserve. When Oliver hired me onto the magazine staff in the early 1970s, he said, “There are just two conditions.” For the life of me, I can’t recall what the
