George White Marston was an American politician, department store owner, and philanthropist. Marston was involved with establishing Balboa Park, the San Diego Public Library System, and San Diego Presidio Park. His contributions to San Diego earned him the affectionate title of "San Diego's First Citizen."

El Presidio Real de San Diego is a historic fort in San Diego, California. It was established on May 14, 1769, by Gaspar de Portolá, leader of the first European land exploration of Alta California—at that time an unexplored northwestern frontier area of New Spain. The presidio was the first permanent European settlement on the Pacific Coast of the present-day United States. As the first of the presidios and Spanish missions in California, it was the base of operations for the Spanish colonization of California. The associated Mission San Diego de Alcalá later moved a few miles away.
