James Strong (August 14, 1822 – August 7, 1894) was an American Methodist biblical scholar and educator, and the creator of Strong's Concordance. He was born in New York City; was Professor of Biblical Literature at Troy University in 1858-61, became Professor of Exegetical Theology at Drew Theological Seminary in 1868 and died at Round Lake, New York.
His best known work is Strong's Exhaustive Concordance of the Bible, first published in 1890, of which new editions are still in print as of 2006. Adaptations (e.g. Strongest Strong's Exhaustive Concordance of the Bible: 21st Century Edition) are also now available.
For the concordance, Strong numbered every Hebrew or Greek root word which was found, for ease of reference. This numbering system (8674 Hebrew roots and 5523 Greek roots) is now used in works by many other writers and is widely available on the webWikipedia article, which is released under the Creative Commons Attribution-Share-Alike License 3.0.
