Elijah Parish Lovejoy was an American Presbyterian minister, journalist, newspaper editor, and abolitionist. After having moved his newspaper from St. Louis, Missouri to Alton, Illinois, he was fatally shot during an attack by a pro-slavery mob. They were seeking to destroy a warehouse owned by Winthrop Sargent Gilman and Benjamin Godfrey, which held Lovejoy's press and abolitionist materials.
According to John Quincy Adams, the murder " a shock as of an earthquake throughout this country". "The Boston Recorder declared that these events called forth from every part of the land 'a burst of indignation which has not had its parallel in this country since the Battle of Lexington.'" When informed about the murder, John Brown said publicly: "Here, before God, in the presence of these witnesses, from this time, I consecrate my life to the destruction of slavery."
