Charles Callahan is one of America's leading organist-composers. A native of Cambridge, Massachusetts, he is a graduate of the Curtis Institute of Music and the Catholic University of America. Well-known as an improvisateur, he made his debut in this realm at the International Eucharistic Congress in 1976. He has collaborated with many of this country's leading conductors as both composer and organist and has worked with noted stage and screen personalities in both theatre and the concert hall.
Orchestras, choirs, chamber music ensembles and soloists all over the world have performed compositions by Dr. Callahan. He has been commissioned to compose music twice by Harvard University. In recognition of his service to the church and his commissioned compositions for Papal visits to the United States, he was awarded in 1999 the Papal Honor of Knighthood in the Order of the Holy Sepulchre of Jerusalem.
In addition to compositions and performances, Charles Callahan is a noted educator and author; his two books on American organ building have become standard reference works.
