Either he was a perfect fit to begin with, or over the years he has taken on many of the characteristics of his workplace, for he now closely resembles his own magazine. He is quite youthful looking, on one hand (probably because he is one of those people who mature early and then never change), and a little old-fashioned on the other. He speaks in perfectly turned paragraphs and may be the last person left in New York to unself-consciously use “indeed” as an exclamation.

He favors gray suits and sweater vests, his telephone manners are impeccable, and he has a bubbling, high-pitched voice that turns a simple “hello” into something that resembles the opening bar of a Broadway show tune. Like his magazine he has an almost insatiable curiosity and is particularly expert on the Revolutionary and Civil Wars, not to mention Coney Island amusement rides at the turn of the last century.

Mr. Snow has been at American Heritage long enough that he can remember when it was an empire in the mid-’60s, employing 400 people, with the magazine as a flagship for what was in effect a publishing company selling books, many of them by some of America’s best-known popular historians, by direct mail. He was managing editor in 1980, when the magazine ceased publishing in hardback (except for subscribers who wanted to shell out extra for what Mr. Snow now calls a “padded, leatheroid edition”), and in 1982 when, bowing to economic necessity, it began soliciting ads.

“We all felt very bad about taking advertising,” Mr. Snow recalled. “But it had the odd effect of making us feel we were in touch with the world. There was a sense of a living connection to a process that was actually sort of fun — or at least it was fun while we were getting ads.”

American Heritage remained more driven by circulation than by ads, however. According to Scott Masterson, a senior vice president at Forbes and president of American Heritage, the magazine was losing money when Forbes bought it in 1986 and then bounced back for a while. But in the late ’90s, Mr. Masterson said, it failed to reap the kind of profits that many magazines did, and after 2001 it experienced the same downturn that afflicted the magazine business in general and had trouble recovering.

Part of the problem was the Internet, Mr. Snow said. “We’re really a general interest magazine,” he said. “We don’t play to a history buff in any narrow sense — like the Civil War re-enactors, for example. They can go on the Web and get thousands and thousands of hits.”
