Henry S. Leverich (1804-1885), along with his brothers, was a merchant and financier in New York City.

Leverich was born July 22, 1804, in Newtown, New York, to Edward Leverich (1763-1835) and Elizabeth Palmer (1771-1827). He received a common school education and left his home about 1820 to enter the then-largest mercantile house in New York City, that of Peter Remsen & Co., as a clerk. The company dealt in a variety of products, including those southern commodities that Leverich and his brother would later specialize in trading.

About 1835, as Peter Remsen & Co. started to wind down their business, Leverich and his brother, Charles P. Leverich (1803-1876), formed a partnership called Leverich & Co. in New York. The brothers in New York and New Orleans worked closely together in building a commission and factorage business. Initially, Leverich & Co. dealt in the products that commission merchants regularly dealt in during the nineteenth century, such as tobacco, foodstuffs, spices, glass and glassware, and soap. The company also dealt in industrial products, such as hemp, hides, and bulk chemicals (specifically brimstone, saltpeter, and indigo). In this early period, most of Leverich & Co.'s bulk trade in Southern produce was in sugar and sugar products, such as molasses and rum. The company expanded to handle all the produce of Southern plantation agriculture, including cotton, sugar, molasses, rice, and occasionally tobacco.

Throughout the Civil War, Henry and Charles Leverich remained loyal to the union. Their elder brother William Leverich (1797-1881), who had lived in New Orleans for over thirty years, sided with the Confederacy due to his sympathy for southern demands regarding slavery and the economy. Family and business ties prevailed over political beliefs, as William Leverich swore he would do anything to protect Leverich & Co. interests. Eventually, northern and southern banks were able to reconcile their differences and continued to operate through the war, despite potential currency issues.

Henry Leverich married Margaret Duncan Gustine (1818-1885) in 1836 in Philadelphia. The couple had three children: Mary Ann (1818-1879), Edward (1839-1886), and James Gustine (1841-1848). Henry's brother, Charles, would marry Margaret's sister, Matilda Duncan Gustine (1816-1896), three years later. Charles would later become the president of the Bank of New York.
