Horatio Gates Spafford was an American lawyer and Presbyterian church elder. He is best known for penning the Christian hymn It Is Well With My Soul following the Great Chicago Fire and the deaths of his four daughters on a transatlantic voyage aboard the S.S. Ville du Havre.

"It Is Well With My Soul", also known as "When Peace, Like A River", is a hymn penned by hymnist Horatio Spafford and composed by Philip Bliss. First published in Gospel Hymns No. 2 by Ira Sankey and Bliss (1876), it is possibly the most influential and enduring in the Bliss repertoire and is often taken as a choral model, appearing in hymnals of a wide variety of Christian fellowships.
