The Apostle of Hungarian Americans. The first Hungarian Roman Catholic priest to arrive with the intention of settling permanently. His birth name was Böehm. His father was Károly Böehm, and his mother was Julianna Urbanszky. There were ten siblings; one of his sisters became a nun.
He completed his high school studies in Selmecbánya, then, already as a minor seminarian, graduated from high school in Esztergom. He studied at the Pázmáneum in Vienna and was ordained a priest on July 16, 1876. Archbishop Kolos Vaszary of Esztergom sent him to the United States in 1892. His arrival (September 1, 1892) is considered the beginning of Hungarian Catholic pastoral work.
He was the organizer of the United Hungarian Society. In 1925, he received the Red Cross Medal of Merit for his charitable work on behalf of the Hungarian community. He was a papal prelate from 1924.
His influence on Hungarian Catholic pastoral work in North America was felt for decades. The number of priests he invited to the United States and assisted can be estimated at around twenty. His pastoral principle—that one must first build a church with a large community hall, then a school, next establish a newspaper, and finally construct the rectory itself—became the method adopted by many of his disciples.
