Poppenhusen Institute is a historic building at 114-04 14th Road in College Point, Queens that housed the first free kindergarten in America.

[2] Along with these classes, the Poppenhusen Institute contained and provided scientific and historical collections, chemical and philosophical apparatus, books, drawings, pictures, statues, and other such means of education and instruction.

[5] The institute housed the Justice of the Peace, the first home of the College Point Savings Bank, German Singing Societies, the first library in the area, a court room, the Sheriff's Office (2 jail cells remain today), as well as the first free kindergarten in the United States which began here on July 1, 1870.

[5] The institute, to this day, has survived and is well known as a recognized trade school, enrolling about 400 men and women a year for evening classes.

[8] A group called the smokeeaters later changed the unit's name to Enterprise Hose Company and established headquarters in the barns adjoining the institute's property on 14th road: this occurred after the engine was retired from service in 1875.
