Prime was born on December 10, 1801 at 54 Wall Street in New York City. He was the eldest son of Nathaniel Prime and Cornelia Prime, who married in 1797. Among his sisters was Cornelia Prime, Emily Prime, Matilda Prime, and Laura Prime. His maternal grandparents were Comfort Sands, the merchant, banker and Continental Congressman, and Elizabeth Sands. His paternal grandparents were Joshua Prime and Bridget Prime. Prime was educated at McCulluck's boarding school in Morristown, New Jersey where his father and other family members were educated.
Career
Five years before his birth, his father organized "Nathaniel Prime, Stock and Commission Broker" which made money buying and selling bank stocks before he opened his own private bank where he allowed customers to deposit money and then loaned it out. In 1808, his father brought Samuel Ward III in as a partner and the firm was renamed Prime & Ward, followed by his uncle Joseph Sands in 1816 when the firm became Prime, Ward & Sands. In 1824, the firm was again reorganized as Prime, Ward, Sands & King when James Gore King became a partner upon his return from England. After Sand's death in 1826, the firm became Prime, Ward & King. In 1826, still a young man, Prime entered the firm and was made a partner of Prime, Ward & Co. upon his father's retirement in 1832. His father, in ill health, committed suicide on November 26, 1840, by cutting his throat. The firm collapsed in 1847, and Prime established the firm of Prime & Co., which consisted of him and his four sons, where he worked until his retirement in 1867, at which point his sons also retired.
