Friedrich Wilhelm Krummacher (born in Moers, France (now Germany), 28 January 1796; died in Potsdam, Prussia (now Germany), 10 December 1868) was a German Reformed clergyman.
The son, after attending the gymnasiums in Duisburg and Bernburg, studied theology at Halle and Jena, and became pastor successively at Frankfurt am Main (1819), Ruhrort (1823), Gemarke, near Barmen (1825), and Elberfeld (1834).
[1][2] He came to New York in 1843, declined a theological professorship in Mercersburg, Pennsylvania, and afterward returned to Germany, eventually settling in Berlin, Prussia.
[1] Although a minister of the Reformed Church, he was a zealous advocate of the older Lutheranism, and gave great offence by his denunciation of rationalists.
Among his numerous works, many of which have been translated into English and Dutch, are: Among his later devotional works are: His sermons were published (Berlin, 1868), and his autobiography (1869) edited by his daughter, which was translated into English (London, 1871).
