Lyman F. Brackett (1852-1937) was born in Charlestown, Massachusetts, and died in Roslindale, Massachusetts. He worked as a professional organist, choir director, piano teacher, performer, composer, and hymnal editor for the Church of Christ, Scientist. He married Alma C. Norton, a fellow musician, in Somerville, Massachusetts, in 1892. Brackett had a music studio in Chickering Hall, in Boston, Massachusetts, where Christian Science services were held from 1885 to 1894, and this may be where he first met Mary Baker Eddy. In the mid-1880s, Brackett participated in various musical events to help raise funds for the construction of The First Church of Christ, Scientist, in Boston. He set poems written by Eddy to music, including "Feed My Sheep," "Christ My Refuge," and "Communion Hymn." There is no record of Brackett studying with Eddy; however, in 1887, Eddy recommended him to be made an honorary member of the Christian Scientist Association. That same year, Brackett was listed as President of the Students' Christian Scientist Association No. 15, Cambridge, Massachusetts, a branch association of the National Christian Scientist Organization. In 1890, he was appointed as chairman and music editor of the seven-person committee authorized to compile the first official Christian Science Hymnal, which was completed and published in 1892. Although Brackett declined Eddy's invitation to serve as the first organist for the newly-erected First Church of Christ, Scientist, in Boston in 1895, he continued to serve the church as music editor of the first revision to the Christian Science Hymnal in 1898.
