Jove Books, formerly known as Pyramid Books, is a paperback publishing company, founded in 1949 by Almat Magazine Publishers (Alfred R. Plaine and Matthew Huttner). The company was sold to the Walter Reade Organization in the late 1960s. It was acquired in 1974 by Harcourt Brace (which became Harcourt Brace Jovanovich) which renamed it to Jove in 1977 and continued the line as an imprint. In 1979, they sold it to The Putnam Berkley Group, which is now part of the Penguin Group.
Phil Hirsch was vice president of Pyramid Books from 1955-1975 and had his name as author or editor on many of Pyramid's books.
In the 1960s Pyramid published a few novelizations of Irwin Allen television shows, including one for Lost in Space and two others for The Time Tunnel.
