Corgan was born in Elk Grove Village, Illinois as the oldest son of William Corgan Sr., a blues/rock guitarist, and Martha Louise Maes Corgan Lutz. His parents had one more child, Ricky, before divorcing in 1970. His father was soon remarried to a flight attendant, and Corgan and his brother went to live with them in Glendale Heights, Illinois. During this time, Corgan alleges he was subject to much physical and emotional abuse by his stepmother. Corgan also developed a protective bond with his younger half-brother, who had special needs as a child. When Corgan's father and stepmother separated, all three children would live alone with the stepmother, with both of Corgan's birth parents living separately within an hour's drive.
