Widely known as the “poor man’s lawyer” in antebellum Boston, John Albion Andrew (1818–1867) was involved in nearly every cause and case that advanced social and racial justice in Boston in the years preceding the Civil War. Inspired by the legacies of John Quincy Adams and Ralph Waldo Emerson, and mentored by Charles Sumner, Andrew devoted himself to the battle for equality. By day, he fought to protect those condemned to the death penalty, women seeking divorce, and fugitives ensnared by the Fugitive Slave Law. By night, he coordinated logistics and funding for the Underground Railroad as it ferried enslaved African Americans northward. In this revealing and accessible biography, Stephen D. Engle traces Andrew’s life and legacy, giving this important, but largely forgotten, figure his due. Rising to national prominence during the Civil War years as the governor of Massachusetts, Andrew raised the African American regiment known as the Glorious 54th and rallied thousands of soldiers to the Union cause. Upon his sudden death in 1867, a correspondent for Harper’s Weekly wrote, “Not since the news came of Abraham Lincoln’s death were so many hearts truly smitten.”
