The U.S. Landmark Non-Fiction series was one of the most popular children’s history book series of the mid-20th century. Robert Leckie was a prolific contributor, authoring or contributing to forty-four volumes covering a vast range of American history. His entries span from the earliest European voyages (The Voyages of Christopher Columbus) through the space program (Americans into Orbit, Walk in Space).
Leckie’s contributions to the Landmark series covered military history, biography, and exploration. He wrote about figures including Ben Franklin, Abe Lincoln, Paul Revere, Davy Crockett, and Clara Barton. His military history entries, such as The Story of D-Day, From Pearl Harbor to Okinawa, and Battle for Iwo Jima, brought the same subjects he covered in his adult histories to a younger audience. The Landmark books remain collected and read today, valued both as historical references and as examples of quality children’s non-fiction from the postwar era.
