==History== In 1938 Irvin Athearn built a detailed O scale model railroad layout in his mother's house, which gained an overwhelming response when he placed an advertisement to sell it. Deciding to make his career selling model railroad supplies, he became a full-time retailer in 1946. Athearn opened a separate facility in Hawthorne, California, in 1948, and that same year he branched into HO scale models for the first time.
