Thomas Potts James was born on September 1, 1803 in Radnor, Pennsylvania to Isaac and Henrietta James (née Potts). The family moved to Trenton, New Jersey when James was nine years old. He and his older brother, John, both intended to enter Princeton College, but the family's financial circumstances prevented them from doing so. Instead, both studied pharmacy and eventually opened a pharmacy together in Philadelphia in 1831.Potts married Isabella Batchelder in December 1851. The couple lived briefly in New Jersey before settling in Philadelphia; they had four children.James likely became interested in botany through its application to medicine. He studied the local flora in his free time and soon turned his focus to cryptogamic botany and bryology in particular. In 1866 James left the pharmacy to devote his time to bryology and the following year moved with his family to Cambridge, Massachusetts. James began corresponding with Swiss bryologist, Leo Lesquereux, in 1848. Their collaboration yielded several publications, including a "Manual of the Mosses of North America," published two years after James's death with final editing and compilation work carried out by Sereno Watson at the Gray Herbarium.James's working life spanned the period of government-sponsored exploration of the continent and he contributed catalogues of mosses for reports on the Clarence King and Wheeler Surveys. He was a member of several scientific societies and a prolific correspondent, exchanging letters with many prominent bryologists and botanists of the day. James suffered a stroke and died on February 22, 1882. He is buried at Mt. Auburn Cemetery in Cambridge, Massachusetts.SourcesGozzaldi MIJ. 1903. Thomas Potts James.
