Born in Albion, Maine in 1811, Lovejoy was one of five brothers born to Emma and Patee Lovejoy, a Congregational minister and farmer. He worked with his family on the farm until he was 18, and his parents encouraged his education. His father was a Congregational minister and his mother was very devout. Lovejoy attended Bowdoin College from 1830-1833. He studied law but never practiced.
Career
Lovejoy migrated to Alton, Illinois, where his older brother Elijah Parish Lovejoy had moved in 1836 from St. Louis, because of hostility to his anti-slavery activities. The older Lovejoy was by then an anti-slavery Presbyterian minister who edited the Alton Observer, an abolitionist newspaper. The younger brother studied theology there. Owen was present on the night of November 7, 1837 when his brother Elijah was murdered while trying to defend the printing press of the Illinois Anti-Slavery Society from an angry mob. He is reported to have sworn on his brother's grave to "never forsake the cause that had been sprinkled with my brother's blood." Owen and his brother Joseph C. Lovejoy wrote Memoir of Elijah P. Lovejoy, which was distributed widely by the American Anti-Slavery Society, increasing Elijah's fame after his death and adding to the abolition cause. Lovejoy served as pastor of the Congregational Church in Princeton, Illinois from 1838 to 1856. During these years, he also organized a number of the 115 anti-slavery Congregational churches in Illinois begun by the American Missionary Association, founded in 1846. His activities brought him increasing public prominence. In 1854 Lovejoy was elected a member of the Illinois State Legislature. He worked with Abraham Lincoln and others to form the Republican Party in the state, and he and Lincoln remained close friends. In 1856, he was elected as a Republican from Illinois as Representative to the 35th United States Congress and succeeding Congresses, serving from March 4, 1857, until his death. In February 1859, Lovejoy responded to the Democrats' charges that by aiding runaway slaves and opposing slavery he was a "negro stealer", saying on the floor of Congress that: Lovejoy was a platform speaker in support of Abraham Lincoln in the famous debates with Stephen A. Douglas. While in Congress, he "introduced the final bill to end slavery in the District of Columbia," long a goal of the American Anti-Slavery Society. He also helped gain passage of legislation prohibiting slavery in the territories. He was one of the few steadfast Congressional supporters of Lincoln during the American Civil War. Lincoln wrote, "To the day of his death, it would scarcely wrong any other to say, he was my most generous friend." In an April 5, 1860 speech before the U.S. House of Representatives, Lovejoy castigated the Democrats and their racist justifications for supporting slavery, saying: As Lovejoy gave his speech condemning slavery, several Democrats in the audience, such as Roger Atkinson Pryor, became irate and incensed. Profoundly objecting to Lovejoy's anti-slavery remarks, the Democrats, brandishing pistols and canes, threatened him with physical harm, to which the Republicans present pledged to defend Lovejoy if the Democrats attempted to attack him. In response to the Democrats' threats, Lovejoy stood firm and responded, "I will stand where I please" and "Nobody can intimidate me." The day after the speech, it was re-printed in 55 newspapers across the country. Regarding the incident, Lovejoy stated in a letter to his wife Eunice that "I poured on a rainstorm of fire and brimstone as hot as I could, and you know something of what that is. I believe that I never said anything more Savage in the pulpit or on the stump."
After his death, an obelisk was erected in Princeton in his honor, and a letter from U.S. President Lincoln said: "Let him have his marble monument along with the well assured and more enduring one in the hearts of all those who love Liberty unselfishly and for all."
