Bishop Francisco Garcia Diego y Moreno, O.F.M.

Bishop of Both Californias, 1840–46

The beginning of Catholicism in California dates from the early explorations of Juan Cabrillo in 1542 and Sebastian Vizcaino in 1602. The priests who accompanied these explorers celebrated Mass here over three centuries ago. The actual founding of El Pueblo de Nuestra Señora de los Ángeles occured in 1781. By 1840 Pope Gregory XVI established a hierarchy in California and named a Franciscan friar, Francisco Garcia Diego y Moreno, as the first bishop of the gigantic Diocese of Both California, extending from the Oregon line to all of Baja California. The bishop died in 1846.

Bishop Joseph Sadoc Alemany, O.P.

Bishop of Monterey, 1850–53

An interim administrator, Father Gonzalez Rubio, headed the diocese for four years and the title was changed to Monterey in 1849. In 1850, Pope Pius IX named Dominican Father Joseph Sadoc Alemany, who was provincial of the Dominicans in the U. S., as bishop of the Monterey Diocese. In 1853 he was named the first Archbishop of San Francisco and peninsular California (Baja) was separated.

He represented the diocese at the First Vatican Council (1869-70), established parochial schools and erected St. Vibiana Cathedral in 1876.

He assisted in the administration of the diocese as coadjutor because of Bishop Mora's failing health, and he assumed complete responsibility for the diocese in 1896.

He organized the St. Vincent de Paul Society in 1904 and acquired The Tidings as the official diocesan publication. During Bishop Conaty's episcopate, the total population doubled, priest numbered 229 and many religious women were serving the diocese in education, hospitals and orphanages.

Between 1948 and 1963, 82 parishes were added and the number of Catholic schools tripled from 147 to 347, about one a month for 15 years. A tremendous wave of immigration brought an influx of Chinese, Japanese, Korean and other Asian ethnic groups as well as a rise in the number of Hispanics and African Americans.
