The Collaberg School (originally known as the Barker School) founded in 1961 was the first 'free school' in the United States based on the model of the Summerhill School in England. The school was located in Stony Point, 30 miles (48 km) from New York City. Collaberg School enrolled between 25 and 50 students from kindergarten through high school in its experimental curriculum. The school closed in 1970 but during its short lifespan was a touchpoint for many of the notable figures of the burst of creative energy that was the 1960s.
