author
Best remembered for the adventure novel that later inspired the cult film Gymkata, this writer led an unusually full life before and beyond books. He moved through Wall Street, wartime intelligence, public speaking, and publishing, which gives his work a distinctly lived-in feel.

by Dan T. Moore
Dan Tyler Moore Jr. was an American author whose career stretched far beyond writing. Born in Washington, D.C., in 1908, he studied at St. Albans and Salisbury School, then earned a physics degree from Yale. Before becoming known for books and stories, he worked in investment banking and later joined the Securities and Exchange Commission, where he helped shape Ohio's securities law.
During World War II, Moore served with the Office of Strategic Services, the forerunner to the CIA. Sources describe him working in the Middle East and North Africa in both official and covert roles, and after the war he went on to business ventures in Turkey and Cleveland. He also became a successful public speaker and wrote widely on fraud, public speaking, and fiction.
Readers most often remember him for The Terrible Game, first published as a short story and then expanded into a novel in the 1950s. That book later became the basis for the 1985 film Gymkata.
