The poem, with the present music, appeared in Asa Hull’s, _The Casket_, published in Philadelphia, 1865, where it is credited to R. Torrey, Jr. To date, no information has come to light concerning the author. He lived a generation earlier than the well known preacher and teacher, R. A. Torrey. In 1868, the hymn was published, anonymously, in _Spiritual Harp_, Boston, a book of songs for congregational use dedicated by the authors to “the Spiritualists and Reformers of the world, love of truth and progress.” Two years later, in 1870, the words and music appeared in England, in the _Sunday School Hymnary_, published by the National Sunday School Union in London. The German version is a free translation made by Ernst Heinrich Gebhardt, 1832-99, a Methodist minister and evangelist, known in Germany, the place of his birth, as the father of German revivalistic and holiness songs. It is superior, in poetic quality and evangelistic appeal, to the English original. Gebhardt was born in Ludwigsburg, Württemberg, July 12, 1832. He prepared to be an apothecary but later decided to go to Chile, South America, to live with relatives. After spending five years on a farm in Chile, he returned to Germany to visit his mother. A shipwreck on the return voyage resulted in a deep spiritual awakening. Arriving in Ludwigsburg, he accompanied his mother to the Sylvester service on New Year’s night, 1859, in the Methodist Church, where he dedicated his life to Christian work. Having decided to become an evangelist, he attended the school for ministers in the Methodist Church at Bremen where his zeal and musical gifts were quickly recognized. He was appointed _Reiseprediger_ and in this capacity served in Ludwigsburg (1860-62), Heilbronn (1862-66), Pforzheim (1866-68), Bremen (1868-71), Ludwigsburg (1871-74), Zurich (1874-77), Strassburg i. E. (1877-81), Biel, Kt. Bern (1880-84), Zwickau (1884-88) and finally in Karlsruhe (1888-99). Gebhardt was married and had a family of nine children. His activities included a trip to the United States, 1881-83, during which he travelled through 30 States. In Brighton, England, he took part in holiness meetings held there, and later travelled with R. Pearsall Smith, of Philadelphia, through Germany and Switzerland, serving as song leader in the evangelistic meetings conducted by Smith. Gebhardt is the author of many original hymns and made over 50 translations from the English, most of them from the Moody and Sankey songs. He compiled numerous song books where his works appeared. “Ich weiss einen Strom” was published in his _Frohe Botschaft_, 1875, a popular book of gospel songs drawn mostly from English sources, both words and music. The third stanza, omitted here, reads: Der Strom ist gar tief und sein Wasser ist klar, Es schmecket so lieblich und fein; Es heilet die Kranken und stärkt wunderbar, Ja, machet die Unreinsten rein!
