Memorial Sloan Kettering Cancer Center (MSK or MSKCC) is a cancer treatment and research institution in Manhattan in New York City. MSKCC is one of 72 National Cancer Institute–designated Comprehensive Cancer Centers. Its main campus is located at 1275 York Avenue between 67th and 68th Streets in Manhattan.
It was formed in 1980 from the merger of the Memorial Hospital for the Treatment of Cancer and Allied Diseases, founded in 1884, and the adjacent Sloan-Kettering Institute for Cancer Research, founded in 1945. The two medical entities had formally coordinated their operations since 1960.

History
Early history of Memorial Hospital (1884–1934)
The hospital was founded in its original building on the Upper West Side of Manhattan in 1884 as New York Cancer Hospital by a group that included John Jacob Astor III and his wife Charlotte. The hospital appointed as an attending surgeon William B. Coley, who pioneered an early form of immunotherapy to eradicate tumors. Rose Hawthorne, daughter of author Nathaniel Hawthorne, trained there in the summer of 1896 before founding her own order, Dominican Sisters of Hawthorne. In 1899, the hospital was renamed General Memorial Hospital for the Treatment of Cancer and Allied Diseases. In 1902, Arabella Huntington made a US$100,000 (equivalent to $3.7 million in 2025) bequest in memory of her late husband Collis Potter Huntington to establish the first cancer research fund in the country, the Huntington Fund for Cancer Research.
Around 1910, James Ewing, a professor at Cornell University's medical college, established a collaboration with Memorial Hospital with the help and funding of industrialist and philanthropist James Douglas, who gave $100,000 (equivalent to $3.5 million in 2025) to endow twenty beds for clinical research, equipment for working with radium, and a clinical laboratory for that purpose. Douglas' enthusiasm and funding for development of radiation therapy for cancer inspired Ewing to become one of the pioneers in developing this treatment. Ewing soon took over effective leadership of clinical and laboratory research at Memorial. In 1916 the hospital was renamed again, dropping "General" to become known as Memorial Hospital for the Treatment of Cancer and Allied Diseases.
The first fellowship training program in the U.S. was created at Memorial in 1927, funded by the Rockefellers. In 1931 the then-most-powerful 900k-volt X-ray tube was put into use in radiation-based cancer treatment at Memorial; the tube had been built by General Electric over several years. In 1931 Ewing was formally appointed president of the hospital, a role he had effectively played until then, and was featured on the cover of Time magazine as "Cancer Man Ewing"; the accompanying article described his role as one of the most important cancer doctors of his era. He worked at the Memorial until his retirement, in 1939. Under his leadership, Memorial became a model for other cancer centers in the United States, combining patient care with clinical and laboratory research, and it was said of him that "the relationship of Ewing to the Memorial Hospital can best be expressed in the words of Emerson, 'Every institution is but the lengthening shadow of some man.' Dr. Ewing is the Memorial Hospital".
Memorial Hospital and the Sloan Kettering Institute (1934–1980)
In 1934, John D. Rockefeller Jr. donated land on York Avenue for a new location. Two years later, he granted Memorial Hospital for the Treatment of Cancer and Allied Diseases (Memorial Hospital) $3.0 million (equivalent to $69.6 million in 2025) and the hospital began their move across town. Memorial Hospital officially reopened at the new location in 1939. In 1945, the chairman of General Motors, Alfred P. Sloan, donated $4.0 million (equivalent to $71.5 million in 2025) to create the Sloan-Kettering Institute for Cancer Research through his Sloan Foundation, and Charles F. Kettering, GM's vice president and director of research, donated ten thousand shares of GM stock worth $2 million and personally agreed to oversee the organization of a cancer research program based on industrial techniques. Both Sloan and Kettering had made considerable fortunes through their stake in Ethyl Corporation, which had made and marketed leaded gasoline since 1923. The originally independent research institute was built adjacent to Memorial Hospital.
In 1948, Cornelius P. Rhoads became the director of Memorial. Rhoads had run chemical weapons programs for the United States Army in World War II, and had been involved in the work that led to the discovery that nitrogen mustards could potentially be used as cancer drugs. He fostered a collaboration between Joseph H. Burchenal, a clinician at Memorial and Gertrude B. Elion and George H. Hitchings at Burroughs Wellcome, who discovered 6 MP; the collaboration led to the development and eventual wide use of this cancer drug.
From the mid-1950s to the mid-1960s Chester M. Southam conducted pioneering clinical research on virotherapy and cancer immunotherapy at MSK; however he conducted his research on people without their informed consent. He did this to patients under his care or others' care, and to prisoners. In 1963 some doctors objected to the lack of consent in his experiments and reported him to the Regents of the University of the State of New York which found him guilty of fraud, deceit, and unprofessional conduct, and in the end, he was placed on probation for a year. Southam's research experiments and the case at the Regents were covered in The New York Times.
In 1960, Memorial Sloan Kettering Cancer Center was formed as a new corporation to coordinate the two institutions, and John Heller, the former director of the National Cancer Institute was named its president. At the end of the 1960s, as the field of pediatric oncology began seeing success in treating children with cancer, Memorial opened an outpatient pediatric day hospital, partly to deal with the growing number of cancer survivors.
Memorial Sloan Kettering Cancer Center (1980–present)
In 1980, Memorial Hospital and the Sloan-Kettering Institute formally merged into a singe entity under the name Memorial Sloan Kettering Cancer Center.
In 1985, Karl Welte, Erich Platzer, Janice Gabrilove, Roland Mertelsmann and Malcolm Moore at the Memorial Sloan Kettering Cancer Center (MSK) purified human G-CSF.
In 1986, the center patented the method of producing and using human G-CSF under the name "human hematopoietic pluripotent colony stimulating factor" (P-CSF). Also in 1986, Shigekazu Nagata's team and Lawrence Souza's team at Amgen cloned the G-CSF gene for production and its clinical use.
In 1990 it entered an agreement with Amgen to receive royalties for the recombinant granulocyte colony-stimulating factor, the basis for neupogen and neulasta, earning the institute over $100 million.
In 2000, former NIH director Harold Varmus became director of MSK. During his tenure, he helped build new facilities, strengthened the bond between MSK's clinical and research arms, and fostered collaborations with other institutions, including Weill-Cornell Medical College and Rockefeller University.
In 2006, MSK opened the Mortimer B. Zuckerman Research Center, a 23-story building that houses over 100 laboratories. In 2009 it opened the Evelyn H. Lauder Breast Center.
In 2010, Craig B. Thompson, an oncologist and researcher, was appointed MSK's president and CEO. The following year, MSK was rated the third most successful nonprofit in terms of FDA-approved drugs and vaccines, behind the National Institutes of Health and the University of California system. In 2012, Thompson appointed José Baselga as physician-in-chief, who directed the clinical side of MSK. That same year, a collaboration with IBM's Watson was announced with the goal of developing new tools and resources to better tailor diagnostic and treatment recommendations for patients. The director of SKI, the research arm of MSK, Joan Massagué was appointed in 2013. Baselga resigned in September 2018 after information came out regarding millions of dollars he received from pharmaceutical companies without disclosing a financial conflict of interest.
