Juan Crespí

Juan Crespí (March 1, 1721 – January 1, 1782) was a Franciscan missionary and explorer of Las Californias. A native of Majorca, Crespí entered the Franciscan order at the age of seventeen. He came to New Spain in 1749, and accompanied explorers Francisco Palóu and Junípero Serra. In 1767 he went to the Baja California Peninsula and was placed in charge of the Misión La Purísima Concepción de Cadegomó.

In 1769, Crespí joined the expedition led by Gaspar de Portolá and Junípero Serra (see Timeline of the Portolá expedition). He traveled in the vanguard of the land expedition to San Diego, led by Captain Fernando Rivera y Moncada, where a presidio and mission were established. Crespí then continued north with Portolá and Rivera to identify the port of Monterey. Because he was the only one of the Franciscans to make the entire journey by land, Crespí became the first official diarist for the missions. He was one of three diarists to document the first exploration by Europeans of interior areas of Alta California.
