The mid twentieth century – specifically, the period from George MacDonald's retirement as editor of "The Truth Seeker" in 1937 until the rise of Madalyn Murray O'Hair in 1963 – was a fallow period in American freethought. Lewis and Haldeman-Julius were essentially the only nationally visible public atheists of this period, and of those two, only Lewis was prominent not only as a publisher but as an activist. As for O'Hair (whom Lewis successfully sued for libel in 1967), her rise to prominence was occasioned by her unexpected victory in a U. S. Supreme Court church-state case, one much like the lawsuits Lewis had repeatedly brought to far more modest success. Lewis played an important role as a bridging figure between the Golden Age of Freethought and the reappearance of atheism on the public stage in the 1960s.
