George Ticknor Curtis was an American historian, lawyer, and writer.

Thomas Sims was an African American who escaped from slavery in Georgia and fled to Boston, Massachusetts, in 1851. He was arrested the same year under the Fugitive Slave Act of 1850, had a court hearing, and was forced to return to enslavement. A second escape brought him back to Boston in 1863, where he was later appointed to a position in the U.S. Department of Justice in 1877. Sims was one of the first slaves to be forcibly returned from Boston under the Fugitive Slave Act of 1850. The failure to stop his case from progressing was a significant blow to the abolitionists, as it showed the extent of the power and influence which slavery had on American society and politics. The case was one of many events leading to the American Civil War.
