As American cities developed, new institutions to accommodate and care for the insane, disabled and criminal were constructed. The Hartford, Connecticut American School for the Deaf opened in 1817, Ossining, New York state prison (now known as Sing Sing) in 1825, the Connecticut State Penitentiary at Wethersfield in 1827, Mount Auburn Cemetery in 1831, the Perkins School for the Blind in 1832, and the Worcester State Hospital in 1833. These institutions attracted the curiosity of American and foreign visitors. The English writer and actress Fanny Kemble, an admirer of the American prison system, was also concerned that nature was being destroyed in favor of new developments. Guidebooks published in the 1830s, 40s and 50s described new prisons, asylums and institutions for the deaf and blind, and urged tourists to visit these sights.
