Fr. Michael Müller C.Ss.R. (1825–1899) was a prolific Catholic writer of the 19th century in the United States. Father Müller always submitted his works to two Redemptorist theologians (as the Redemptorist Congregation's rule required) and to his religious superiors before publication.
Müller ("Mueller" in English spelling) was born on December 18, 1825, in the village Brück in the German Eifel region. He joined the Congregation of the Most Holy Redeemer and was under the spiritual direction of Joseph Passerat. In 1851, Frater Mueller was one of eleven clerics and priests chosen by the American Redemptorist Provincial to be sent to the United States. He completed his theological studies in Cumberland, Maryland, and was ordained on March 26, 1853, by the Redemptorist Bishop of Philadelphia, John Nepomucene Neumann.
After ordination, Father Mueller took spiritual care of professed students at Cumberland. Three years later, he was appointed Superior and Novice Master at the Congregation’s foundation in Annapolis, Maryland. In subsequent years, he served the Redemptorist communities of America in a variety of capacities, including Consultor to the Provincial.
