Admitted to practice before the U.S. Supreme Court on Feb 1, 1865, via a motion by Senator Charles Sumner. Before becoming a lawyer in 1861, Rock was a teacher, one of the first Black dentists, and one of the first Black doctors after earning his M.D. in 1852. A fierce advocate against slavery and racial injustice, he recruited Black soldiers for the 54th Massachusetts Regiment during the Civil War.

This series spotlights stories that history nearly erased, but legacy refused to forget. Recognizing Black achievement during Black History Month is not only about honoring triumph, but about reclaiming narratives of resilience, intellect, and humanity that were, in some cases, deliberately buried-and when it comes to pioneering attorney John S. Rock, it means honoring a 19th-century trailblazer who broke barriers at the United States Supreme Court and used his voice to fight for abolition and equal rights. John S. Rock lived from October 13, 1825, until December 3, 1866. He was a pioneering abolitionist, physician, dentist, lawyer, and civil rights advocate who made history in 1865 as the first Black man admitted to practice before the Supreme Court of the United States. His life, though tragically short, embodied the intellectual brilliance, resilience, and political courage that defined Black activism during the Civil War era. Rock's achievements were extraordinary not only because of the barriers he broke, but also because of the breadth of his professional accomplishments in a society structured to deny Black Americans education, citizenship, and legal standing. Born free in Salem, N.J., to formerly enslaved parents, Rock grew up in a period when free Black Americans in the North still faced severe discrimination. He was largely self-educated in his early years and began working as a teacher at a young age. His intellectual gifts were evident early on; he pursued further education despite limited opportunities for Black students. Rock eventually studied medicine and dentistry, fields in which very few African Americans were allowed to practice. He earned a medical degree in the early 1850s and established himself as both a physician and a dentist in Philadelphia and later Boston. Rock's move to Boston proved transformative. The city was a hub of abolitionist activism, and Rock became deeply involved in the movement to end slavery and secure equal rights for Black Americans. Though already trained as a physician, chronic health problems-especially tuberculosis-made it difficult for him to continue practicing medicine. He turned his focus toward law, studying privately and gaining admission to the Massachusetts bar in 1861. At a time when Black lawyers were almost nonexistent, Rock's admission to the bar was itself a significant milestone. In Boston, Rock became known as a powerful and eloquent orator. His speeches combined legal reasoning, moral conviction, and sharp wit. He advocated not only for the abolition of slavery but also for full citizenship rights for Black Americans, including suffrage. Unlike some white abolitionists who focused narrowly on ending slavery, Rock insisted that emancipation without political rights would leave Black Americans vulnerable and subordinated. He argued forcefully that Black men deserved the right to vote and to serve in the military, linking citizenship to participation in the nation's defense and political life. Here is an example of a powerful speech he delivered to the Massachusetts Anti-Slavery Society in Boston on Jan. 23, 1862 via BlackPast.org: "I am here not so much to make a speech as to add a little more color to this occasion. [Laughter.] I do not know that it is right that I should speak, at this time, for it is said that we have talked too much already; and it is being continually thundered in our ears that the time for speech-making has ended, and the time for action has arrived." "Perhaps this is so. This may be the theory of the people, but we all know that the active idea has found but little sympathy with either of our great military commanders, or the national Executive; for they have told us, again and again, that "patience is a cure for all sores," and that we must wait for the "good time," which, to us, has been long a-coming." During the Civil War, Rock actively supported the enlistment of Black soldiers in the Union Army. He believed military service would demonstrate Black Americans' loyalty and strengthen their claim to equal rights. His speeches encouraged recruitment and emphasized that African Americans were fighting not only for the Union but for their own freedom and dignity. Rock also criticized discriminatory policies within the Union Army, including unequal pa
