for 50 years. He joined the faculty of Union Theological Seminary in 1912, where he remained until his retirement in 1945; he founded the institution's School for Sacred Music there in 1928. This school offered the first graduate degrees in sacred music in the United States. He suffered a heart attack in 1955. His wife Helen died in 1957. He remarried in 1963 to Lois Stice at Brick Presbytarian. He played regularly at the World's Fairs, starting with Chicago in 1893 through Montreal's in 1967. He and his first wife co-wrote a large amount of sacred music, as well as a general-audience music appreciation book titled Excursions in Musical History. While he composed large-scale pieces, including at least one organ symphony, he was better known as an arranger and pedagogue; his 1922 publication Technique and Art of Organ Playing was a standard reference work which went through several editions in his lifetime, and he edited a general-use hymnal for the Presbyterian Church in the United States of America in 1933. Late in life he and his wife collaborated on an edition of anthems written by early Moravian settlers in the United States. Legacy A music festival in honor of Clarence Dickinson and in memory of his wife Helen Dickinson was held on April 27, 1958 in New York's Riverside Church. Many choirs, conductors, organists, and soloists participated, among them Virgil Fox and Leo Sowerby. Sowerby's organ work Eternal Light was written for the occasion and given its premiere by Dickinson. At this festival he was given the sobriquet the Dean of American Church Music. The Journal of Church Music's October 1969 issue was a memorial issue dedicated to Dickinson. His widow Lois donated his archives to William Carey College. After Lois' death in 1972, her sisters gifted the entire contents of Dickinson's study to the college. The collection includes a desk that once belonged to his cousin Emily Dickinson, one of the rare surviving copies of Jeremiah Ingalls' A Songster's Companion, and correspondence with musical and church figures of his day. The college named the Clarence Dickinson Memorial Library of Church Music in his honor. The American Guild of Organists named the Clarence Dickinson Society, its legacy and planned giving program, in his honor. Sculptor Paul Fjelde created a portrait of Dickinson in 1959. Several works are dedicated to Dickinson, including: The Vanderpoel Compositions, a set of songs for voice
