19th century In 1857, a group of community leaders recognized the need for medical services among the immigrant community and founded the German Dispensary. In 1862, the dispensary moved to larger quarters at 8 East
3rd Street.
The German Hospital of the City of New York was incorporated by the New York State Legislature on April 13, 1861, and its first board of directors was organized on February 15, 1862. A plot of ground situated on
Park Avenue and 77th Street was leased to the hospital by the city for 50 years at a nominal rent, and it purchased six additional lots on 76th Street. The plan was to erect two pavilions, extending along 77th Street, from Park to Lexington Avenues, with an administration building between them. The corner-stone of the western pavilion was laid on September 3, 1866. Completion was delayed by a shortage of funds, and the hospital opened on September 13, 1869. On March 26, 1866, the state legislature made the German Dispensary a branch of the German Hospital. A hospital annex, at the corner of 77th Street and Lexington Avenue, also donated by the Ottendorfer family, opened in 1901. The new dispensary building was opened on March 16, 1907. In 1908, a new isolation pavilion was inaugurated, as well as a pavilion for tuberculosis patients. In 1910, a separate building for intrathoracic surgery was begun on Lexington Avenue, adjoining the German Hospital Training School for Nurses. Ottendorfer's daughter donated $100,000 for the creation of the Abraham Jacobi Division for Children. The capacity of the German Hospital in 1915 was 310 beds. In April 1931, the hospital completed a new $2.5 million, 11-story building, with a facade made of light brick with
limestone trim, on the 76th Street side of the hospital. The new building replaced two apartment houses and several workshops. In December 1931,
Winston Churchill was hospitalized there for treatment of injuries suffered when he was hit by a car after failing to look left when crossing
Fifth Avenue. The pioneering children's division, founded by Dr. Abraham Jacobi, was housed on the 11th floor, with other patient rooms on the 4th through 9th floors, and operating rooms on the 10th floor. Another two-story building, containing a ward service, lecture hall, and swimming pool, was added next to the main building on the 76th Street side in 1936, at a cost of $150,000. By 1939, the hospital had annually treated 12,115 patients with bed care, and another 23,099 visited the dispensary for treatment. Adding accident room patients, the hospital treated over 53,000 people in 1939. Because some care was given for free or part-pay, the hospital often ran an operating deficit, just as it did in 1939, when it lost $163,029, down a loss of over $200,000 the previous year, in 1938. The hospital's operating loss grew to $284,692 in 1945, which was then a record high. Due to a lack of funds, an anticipated additional new building was delayed for over 20 years, when the Second Century Development Program, designed to raise $10 million, was led by the hospital's president, James Wickersham. In 1957, on the hospital's 100th anniversary, it opened a $4.5 million, 12-story building on Park Avenue at 77th Street, with a glass and aluminum facade, and a capacity of 180 patient beds. The new building, named the Wollman Pavilion, also housed a mental health unit, and an entire floor was allocated for research on speech and hearing disorders, epilepsy, and hemophilia. In 1964, the Charles R. Lachman Community Health Center was added on the south side of 77th Street, between the Wollman Pavilion and the William Black Hall of Nursing, which opened in 1962 (the School of Nursing closed in 1973). The hospital opened its largest building, 12 stories tall, in 1976, located at Park Avenue and 76th Street, replacing the Ottendorfer Dispensary, at a cost of $20 million. The modern brick masonry structure, with a fortress-like facade, stood in stark contrast in architectural style of the rest of the hospital's buildings. The new building added 180 patient beds for an overall capacity of 690 beds. In 1943, the hospital sent a medical unit to England to maintain station hospitals for military personnel. Throughout the remainder of
World War II, hospital staff members served in all theaters of war, including with combat forces in the European theater of operations after
D-Day. In 1998, a jury awarded $49 million in an
obstetrics case against the hospital, which was one of the largest
medical malpractice verdicts in New York City history at that time.
21st century The hospital's building underwent masonry and roof restorations, conducted by Merrit Engineering Consultants, P.C., from 2007 to 2009. Façade restoration, waterproofing, and structural steel repairs were also conducted. On May 19, 2010, the hospital announced that an agreement had been finalized for it to join
Northwell Health. In 2014, the old St. Vincent Hospital building that closed in 2010, became
Lenox Hill HealthPlex, Manhattan's first
freestanding emergency department. This facility is located at 30 7th Avenue between West 12th and 13th streets. This emergency department sees patients whether they come as a walk-in or via an ambulance. In 2020,
Netflix released a documentary series,
Lenox Hill, which was filmed at the hospital. The plan included a tower. Northwell's proposal, particularly the tower, was controversial among neighborhood residents, and a community group was formed to fight the plans. That April, the local
Manhattan Community Board 8 recommended that the city not enact a
zoning change that would allow the tower to proceed. In July 2025, the CPC tentatively approved Northwell Health's plan to spend $2 billion redeveloping the Lenox Hill Hospital site. the
New York City Council approved the scaled-back version of the project that August. As part of the plan, the hospital would be increased to 475 beds, each within their own room. In addition, the new hospital would include a new maternal-care department and an expanded emergency department. == Significance ==
