John Nepomucene Neumann (Czech: Jan Nepomucký Neumann, German: Johann Nepomuk Neumann; March 28, 1811 – January 5, 1860) was a Catholic priest from Bohemia.
He immigrated to the United States in 1836, where he was ordained and later joined the Redemptorist order and became the fourth Bishop of Philadelphia (1852–1860).
He is the first United States bishop (and to date the only male U.S.
citizen) to be canonized.
While Bishop of Philadelphia, Neumann founded the first Catholic diocesan school system in the United States.
