Ronald Wilson Reagan was born on February 6, 1911, in a commercial building in Tampico, Illinois, as the younger son of Nelle Clyde Wilson and Jack Reagan. Nelle was committed to the Disciples of Christ, which believed in the Social Gospel. She led prayer meetings and ran mid-week prayers at her church when the pastor was out of town. Reagan credited her spiritual influence and he became a Christian. According to American political figure Stephen Vaughn, Reagan's values came from his pastor, and the First Christian Church's religious, economic and social positions "coincided with the words, if not the beliefs of the latter-day Reagan". Jack focused on making money to take care of the family, but this was complicated by his alcoholism. Neil Reagan was Reagan's older brother. Together, they lived in Chicago, Galesburg, and Monmouth before returning to Tampico. In 1920, they settled in Dixon, Illinois, living in a house near the H. C. Pitney Variety Store Building.
Reagan attended Dixon High School, where he developed interests in drama and football. His first job involved working as a lifeguard at the Rock River in Lowell Park. In 1928, Reagan began attending Eureka College at Nelle's approval on religious grounds. He was a mediocre student who participated in sports, drama, and campus politics. He became student body president and joined a student strike that resulted in the college president's resignation. Reagan was initiated as a member of Tau Kappa Epsilon Fraternity and served as president of the local chapter. Reagan played at the guard position for the 1930 and 1931 Eureka Red Devils football teams and recalled a time when two black football teammates were refused service at a segregated hotel; he invited them to his parents' home nearby in Dixon and his parents welcomed them. At the time, his parents' stance on racial questions were unusually progressive in Dixon. Reagan himself had grown up with very few black Americans there and was unaware of a race problem.
