American evangelist. Becoming a Congregationalist in 1856, Moody embarked on evangelistic work in connection with his Sunday School in Chicago. In 1870 he was joined by Ira David Sankey (1840–1908), who regularly accompanied his preaching with singing and organ-playing. They toured both America and Britain. The ‘Sankey and Moody Hymn Book’ (1873) incorporated many of the songs used by Sankey and other revivalists. Moody founded various institutions in the USA.
