In 1894 Charles Chapman, a retired Chicago publisher and a descendant of John "Johnny Appleseed" Chapman, purchased an orange orchard in eastern Fullerton. The Valencia variety of oranges he promoted from his Santa Ysabel Ranch, well suited to the local climate, proved a boon to producers; Fullerton boasted more orange groves than any other municipality in the United States. Cultivation of walnuts and avocados also flourished, and the Western railroad town became an agricultural center. Fullerton was incorporated in 1904, but not officially recognized until 1907, due to conflicts at that time.
