Dwight Lyman Moody (February 5, 1837 - December 22, 1899), also known as D. L. Moody, was an American evangelist and publisher connected with the Holiness Movement, who founded the Moody Church, Northfield School and Mount Hermon School in Massachusetts (now Northfield Mount Hermon School), Moody Bible Institute and Moody Publishers. One of his most famous quotes was "Faith makes all things possible... Love makes all things easy." Moody gave up his lucrative boot and shoe business to devote his life to revivalism, working first in the Civil War with union troops through YMCA in the United States Christian commission. In Chicago, he built one of the major evangelical centers in the nation, which it is still active. Working with singer Ira Sankey, he toured the country and the British Isles, drawing large crowds with a dynamic speaking style that preached God's love and friendship, kindness and forgiveness rather than hellfire and condemnation.

During a trip to the United Kingdom in the spring of 1872, Moody became well known as an evangelist. Literary works published by the Moody Bible Institute claim that he was the greatest evangelist of the 19th century.[10] He preached almost a hundred times and came into communion with the Plymouth Brethren. On several occasions, he filled stadia of a capacity of 2,000 to 4,000. According to his memoir, in the Botanic Gardens Palace, he attracted an audience estimated at between 15,000 and 30,000.[11]
That turnout continued throughout 1874 and 1875, with crowds of thousands at all of his meetings. During his visit to Scotland, Moody was helped and encouraged by Andrew A. Bonar. The famous London Baptist preacher, Charles Spurgeon, invited him to speak, and he promoted the American as well. When Moody returned to the US, he was said to frequently attract crowds of 12,000 to 20,000 were as common as they had been in England.[12] President Grant and some of his cabinet officials attended a Moody meeting on January 19, 1876. He held evangelistic meetings from Boston to New York, throughout New England, and as far west as San Francisco, also visiting other West Coast towns from Vancouver, British Columbia, Canada to San Diego
