Brooklyn Hospital, founded in 1845. The Brooklyn Hospital was founded as the "Brooklyn City Hospital" in May of 1845, supposedly following an incident in which a man from Buffalo, New York broke his leg at Fulton Street, in proximity to nearby Brooklyn City Hall. The hospital played a major part in providing treatment and aid for soldiers of the Union Army during the Civil War. It continued to play the role of carrying for sick and wounded soldiers in the Spanish-American War and both World Wars. In 1880, the hospital established the first nursing school in Brooklyn and the first in the State of New York. This was made possible by a generous donation by the women of the Fruit and Flower Mission. The hospital also installed the second Electrocardiograph in Brooklyn in the year 1926.
