http://www.bklyn-genealogy-info.com/Directory/1935.Hosp.NYState.html Although this is a list of hospitals in NYS in 1935, you might google the TB sanitariums individually to determine when each facility opened. The essential treatment for TB then, due to its highly contagious nature, was to remove those stricken from the pollution and stench of the cities, and send them folks off to "the country" for fresh air and sunshine. This is a pulmonary infection. In 1900, Queens, Nassau, areas of Brooklyn, Bronx, Westchester, and Rockland counties were considered "county." Other such sanitariums were located off northern train routes, in Poughkeepsie, Goshen, and in the Adirondeck [sp?] and Catskill Mountains. I've even seen antique photos of TB facilities where patients were bundled in blankets, to lay out on open porches, to catch the sunrays on a cold winter's day! Barb
