Peter Verdaguer y Prat (Sant Pere de Torelló, December 10, 1835 - Texas, October 26, 1911) was a Catalan-born prelate of the Roman Catholic Church. He served as Vicar Apostolic of Brownsville from 1890 until his death in 1911.
Peter Verdaguer y Prat was born in Sant Pere de Torelló, county of Osona in the Province of Barcelona, to Francisco Verdaguer and Maria Prat Verdaguer. He attended the seminaries of Vic and Barcelona before coming to the United States, where he completed his theological studies at St. Vincent's Seminary in Cape Girardeau, Missouri. He was ordained to the priesthood by Bishop Thaddeus Amat y Brusi, C.M., on December 12, 1862. He then did pastoral work in the Diocese of Monterey-Los Angeles, California, serving as a missionary and pastor of San Bernardino and in Los Angeles.
On July 25, 1890, Verdaguer was appointed the Vicar Apostolic of Brownsville, Texas, and Titular Bishop of Aulon by Pope Leo XIII. He received his consecration on the following November 9 in Barcelona from Bishop Jaime Catalá y Albosa, the Bishop of Barcelona, with Bishops José Morgades y Gili and José Meseguer y Costa serving as co-consecrators.
Returning to the United States, Verdaguer arrived in his new vicariate the following spring. He then removed the episcopal see from Corpus Christi to Laredo. He invited several religious institutes into the vicariate, including the Sisters of Mercy, Claretians, and Sisters of Charity of the Incarnate Word. He opened two hospitals, several churches and parochial schools, and an orphanage. He also increased the number of Catholics by 40,000, and the number of priests from 10 to 32.
