Robert Robinson (September 27, 1735 – June 9, 1790) was a determined English Dissenter, an influential Baptist and scholar who made a lifelong study of the antiquity and history of Christian Baptism. He was also author of the hymns "Come Thou Fount of Every Blessing" and "Mighty God, while angels bless Thee," the former of which he wrote at age 22 after converting to Methodism. The latter was later set to music by Dr John Randall, Music Professor at Cambridge. Source : Wikipedia
