Harry Bollback (1925–2021) was an American Christian musician, pianist, composer, and musical director. He was born in Brooklyn, New York, and was closely associated for many decades with the international Christian organization Word of Life, whose work he helped shape alongside Jack Wyrtzen.

After completing his education at the Philadelphia College of Bible, Bollback initially worked as a missionary in Brazil, where he established youth camps and musical programs. Later, he worked in the United States as a musician, evangelist, and producer, writing numerous spiritual songs as well as larger-scale musical productions and gospel cantatas.

Among his best-known works is the Christmas carol “Ring the Bells,” which was released by Singspiration Music in 1958. Bollback’s music combines catchy melodies with a festive, choral character and was widely used in churches, youth programs, and evangelistic events.

Harry Bollback died in January 2021 at the age of 95.
