Brown Memorial Park Avenue Presbyterian Church of Baltimore, Maryland, U.S., is a large, Gothic Revival-style church built in 1870 and located at Park Avenue and Lafayette Avenue in the city's Bolton Hill neighborhood. Named in memory of a Baltimore financier, the ornate church is noted for its exquisite stained glass windows by renowned artist Louis Comfort Tiffany, soaring vaulted ceiling, and the prominent persons associated with its history. Maltbie Babcock, who was the church's pastor 1887–1900, wrote the familiar hymn, This is My Father's World. Storied virtuoso concert performer Virgil Fox was organist at Brown Memorial early in his career (1936–1946). Called "one of the most significant buildings in this city, a treasure of art and architecture" by Baltimore Magazine, the church underwent a $1.8 million restoration between 2001 and 2003. It is part of the Presbyterian Church (U.S.A.) denomination. History The Brown Memorial Presbyterian Church building was dedicated on December 4, 1870, in memory of George Brown, chairman of the Baltimore-based investment firm, Alex. Brown & Sons, and one of the founders of the pioneering Baltimore and Ohio Railroad in 1827. Construction was funded by a gift of $150,000 from his widow, Isabella McLanahan Brown, an amount equivalent to more than $4 million in 2009. George Brown was described by a Baltimore historian as a successful businessman and civic leader who "regarded religion as preeminent above all other things and loved his church with all the ardor of his noble nature". John Sparhawk Jones was the church's first pastor, serving from 1870 to 1884. Several of his collected sermons were later published in such books as Seeing Darkly, The Invisible Things, and Saved by Hope. The church's pastor between 1887 and 1900 was Maltbie Babcock, who was formally installed on September 28, 1887. His biography in a 1910 encyclopedia described him as "a fluent speaker, with a marvelous personal magnetism which appealed to all classes of people, and the influence of which became in a sense national. His theology was broad and deep ... he reached people in countless ways and exerted everywhere a remarkable personal magnetism ... [having] an unusually brilliant intellect and stirring oratorical powers that commanded admiration". While at Brown, he led fund-raising efforts to assist Jewish refugees from Russia who were victims of an anti-Jewish pogrom. He was also a popular speaker with students at Johns Hopkins University. Under Babcock, the church acquired additional property
