New Albany grew rapidly and was the largest city in Indiana from 1816 until 1860 when overtaken by Indianapolis. Before the Civil War, over half of Hoosiers worth over $100,000 lived in New Albany, making it by far the wealthiest part of the state. The steamboat industry was the engine of the city's economy during the mid-19th century. Fueled by abundant forests for lumber, at least a half-dozen shipbuilders were in operation and turned out a multitude of steamboats and packet boats, including the "Robert E. Lee", "Eliza Battle", the "Eclipse", and the "A.A. Shotwell". Shipbuilding was accompanied by a wide range of ancillary business including machine shops, foundries, cabinet and furniture factories, and silversmith shops. Its second largest business was the American Plate Glass Works.
