In California's Spanish and Mexican eras there was not much formal education. The nearest university was that of Guadalajara, founded in 1792. The Híjar-Padrés colony of 1834 brought teachers who might have been the province's first permanent residents to hold professional qualifications. Richard Henry Dana Jr. visited that same year on leave from Harvard College. In 1846 the U.S. acquired California. The University of California, whose creation became more urgent as more native sons were born, graduated its first class in 1873.
I want to know about the first person or persons from California that went away to university, or studied at one of the University of California's predecessor institutions, or another school in the state. The sons of established businessmen like Hartnell, Larkin, and Stearns seem like candidates. Perhaps some brainy kid was even sent to Guadalajara decades before.
