Junipero Serra y Ferrer (1713 - 1784) Spanish Roman Catholic priest and missionary of the Franciscan Order. He is credited with establishing the Franciscan Missions in the Sierra Gorda, a UNESCO World Heritage Site. He later founded a mission in Baja California and the first nine of 21 Spanish missions in California from San Diego to San Francisco, in what was then Spanish-occupied Alta California in the Province of Las Californias, New Spain.
