William Churchill Hammond (November 25, 1860 – April 15, 1949)[1] was an American organist, choirmaster, and music educator.

He is noted for being one of the founding members of the American Guild of Organists, and for a lengthy tenure on the faculty of Mount Holyoke College.

In 1885, at the age of 25 he became organist and music director of Holyoke's Second Congregational Church,[a] a post that he served for nearly 60 years.

[3] Among his pupils was John Shea, who would later write Notre Dame's Victory March, first playing it for his former teacher on the congregational church's organ in 1908.

[3][6][7] Throughout his career Hammond himself would give more than 1,200 local recitals as well as organize and tour Mount Holyoke's Carol Choir to venues across the country, including the White House.
