There were only 250 inhabitants in 1836, many from Pennsylvania, but the population had reached about 1600 by 1855, with some 70% originally from Germany. By then, the area had eight hotels and taverns. Some of these hotels, such as the North American Hotel (later called the Kress and still standing) from the 1840s and the later Del Monte (most successful in the 1890s) and the Sulphur Springs, were built to accommodate visitors who arrived via the Great Road to benefit from the mineral springs. The high sulphur content was believed to be useful for those with arthritis and rheumatism.
