He found fame when his humor book
Low Man on a Totem Pole (1941) became a bestseller during
World War II. It was not only popular on the home front but also read on troop trains and at military camps. Featuring an introduction by his friend
Fred Allen, it eventually sold over a million copies.
Damon Runyon called it, "Rich funny stuff, loaded with laughs." As noted by
Eric Partridge in
A Dictionary of Catch Phrases, the book's title became a
catchphrase for the least successful individual in a group. With his newfound financial freedom, he left the daily newspaper grind for life as a freelance author scripting for radio and also wrote (for six months)
The Totem Pole, a daily column for
United Features Syndicate; made personal appearances; and worked on his next book,
Life in a Putty Knife Factory (1943), which became another bestseller. He spent eight months in
Hollywood as a screenwriter for
Paramount Pictures and wrote about the experience in
Lost in the Horse Latitudes (1944). His first three books were widely circulated around the world in
Armed Services Editions. The popularity of those titles kept Smith on the
New York Herald Tribune Best Seller List for 100 weeks and prompted a collection of all three in
3 Smiths in the Wind (1946). By the end of the war, Smith's fame as a humorist was such that he edited
Desert Island Decameron (1945), a collection of essays and stories by such leading humorists as
Dorothy Parker,
Robert Benchley and
James Thurber. Histories of the
Manhattan Project mention
Desert Island Decameron because
Donald Hornig was reading it when he was sitting in the
Trinity Test tower and babysitting the atomic bomb on July 15, 1945, the stormy night prior to the first nuclear explosion. ==Later writing==
