SecondBishop ofMonterey and Los Angeles,California, U.S., b. 31 December, 1810, atBarcelona,Spain; d. atLos Angeles,California, 12 May, 1878. He joined theLazarists in early manhood and wasordained apriest at the house of that Congregation inParis, in 1838. He came to theUnited States in 1838 and worked in the missions inLouisiana. He was master ofnovices in the houses of theLazarists inMissouri and Philadelphia in 1841-47, and on the promotion ofBishop Alemany of Monterey to beArchbishop ofSan Francisco, Father Amat was named to succeed him. He wasconsecratedBishop of thediocese inRome, 12 March, 1854. There were seventeenpriests in the diocese then to care for the spiritual needs of a very mixed population largely of Spanish origin. The opening of the mining era of the early fifties brought a large accession of other settlers, and Bishop Amat, visitingEurope to obtain additional aid for hisdiocese, brought backLazaristpriests and Sisters of Charity with him. He was given permission by theHoly See, in 1859, to call himselfBishop ofLos Angeles, and changed his residence to that city. There, under his inspiration, theLazarists opened St. Vincents College and theFranciscan Brothers took charge of theparochialschools. The Sisters of the Immaculate Heart of Mary were also introduced. A serious spinal affection forced Bishop Amat to ask for a coadjutor and hisvicar-general, the Rev. Francis Mora, was soconsecrated 3 July, 1873. He had begun a newcathedral and lived to see it dedicated 9 April, 1876. When he died, at the age of sixty-seven, the progress of thediocese under hisjurisdiction was indicated in the increase to 51priests, 32churches, 15chapels, and 32 stations, 6 academies and substantialparochialschools, asylums, and othercharitable institutions.
