Jackson Sanatorium (also known as, Our Home on the Hillside, Home Hygienic Institute, Jackson Health Resort) was a historical mineral spa in Dansville, Livingston County, New York, attracted many prominent people to Dansville for the water cure.[1] Operated for many years by the Jackson family,[2] its operations dated to 1852 when water cures were in growing favor. Dansville had a spring gushing from the hillside, "All Healing Spring", which was supposed to have curative properties. As these water cures were located near some noted springs, "the Home on the Hillside" was created and the institution was ready for occupancy in 1853. In 1890, the old name of the company, "Our Home Hygienic Institute" was changed to "The Jackson Sanitorium". In 1904, the name was again changed to "The Jackson Health Resort".[3][4]Granula was invented at the Jackson Sanatorium.[5]
