Mr. Adam (1946) is the first novel written by Pat Frank, dealing with the effects of a nuclear mishap causing worldwide male infertility. Published by J. B. Lippincott Company, it was also released as an Armed Services Edition, a paperback by Pocket Books in 1948, and again in 1959 by Pocket Books with the tag Mr. Adam Was Wanted By Every Woman in the World. All told, it sold over 2 million copies.

Harry Hart "Pat" Frank was an American newspaperman, writer, and government consultant. Perhaps the “first of the post-Hiroshima doomsday authors,” his best known work is his post-apocalyptic novel Alas, Babylon (1959), which depicted the outbreak of a nuclear war and the struggles of its survivors in a small, central Florida town.
