Founded in 1811,2 the original hospital was designed by the famous American architect Charles Bulfinch.7 It is the third-oldest general hospital in the United States; only Pennsylvania Hospital (1751) and NewYork-Presbyterian Hospital's predecessor New York Hospital (1771) are older.2John Warren, Professor of Anatomy and Surgery at Harvard Medical School, spearheaded the move of the medical school to Boston. Warren's son, John Collins Warren, a graduate of the University of Edinburgh Medical School, along with James Jackson, led the efforts to start the Massachusetts General Hospital, which was initially proposed in 1810 by Rev. John Bartlett, the Chaplain of the Almshouse in Boston. Because all those who had sufficient money were cared for at home, Massachusetts General Hospital, like most hospitals that were founded in the 19th century, was intended to care for the poor.8 A 30-year-old sailor was the first patient admitted to the hospital on September 3, 1821.9 During the mid-to-late 19th century, Harvard Medical School was located adjacent to Massachusetts General Hospital.
Walter J. Dodd established the radiology department at the hospital. From just after the discovery of x-rays in 1895, until his early death in 1916 from metastatic cancer caused by multiple radiation cancers he oversaw the radiology department. He also underwent over 50 surgical procedures at the hospital to treat his radiation injuries, from skin grafts to amputations.10
The first American hospital social workers were based in the hospital.11
The hospital's work with developing specialized computer software systems for medical use in the 1960s led to the development of the MUMPS programming language, which stands for "Massachusetts General Hospital Utility Multi-Programming System", an important programming language and database system heavily used in medical applications such as patient records and billing. A major patient database system called File Manager, which was developed by the Veterans Administration (now the Department of Veterans' Affairs), was created using this language.
Early use of anesthesia
Monument in Boston commemorating Morton's demonstration of ether's anesthetic use
It was in the Ether Dome of MGH in October 1846,7 that a local dentist, William Thomas Green Morton, was invited to perform a public demonstration of the administration of inhaled ether to produce insensibility to pain during surgery.7 Several years prior, Dr. Crawford Long of Danielsville, Georgia had given ether for surgery, but his work was unknown outside Georgia until he published his experience in 1849. On 16 October 1846, after administration of ether by Morton, MGH Chief of Surgery, John Collins Warren, painlessly removed a tumor from the neck of a local printer, Edward Gilbert Abbott.7 Upon completion of the procedure, which was without screaming or restraint, the usually skeptical Warren reportedly quipped, "Gentlemen, this is no humbug." News of this "anesthesia" invention rapidly traveled within months around the world.12
A reenactment of the Ether Dome event was painted in 2000 by artists Warren and Lucia Prosperi. They used the then-MGH staff to pose as their counterparts from 1846.13 The Ether Dome still exists7 and is open to the public.
An anesthesia department was established at the MGH in 1936 under the leadership of Henry Knowles Beecher.
First successful replantation of a severed limb
On 23 May 1962, under the direction of Ronald A. Malt, a team of surgeons successfully accomplished the first replantation of completely severed limb.14
While attempting to hitch a ride on the back of a freight train, Everett Knowles (1950–2016), aged 12 at the time, hit an abutment when the train lurched, severing his arm completely at the shoulder. He and his arm were rushed to MGH, where a 30 year old Malt conducted the team of surgeons. Some doctors prepared Everett for surgery, while others worked on the separated arm. First, they rejoined the "chaotically mangled blood vessels, then the bone and finally the skin". In the time since the accident, the arm had grown a "deathly gray", but grew steadily pink as the surgery progressed and blood vessels were reattached. The nerves would be reconnected in a later surgery.1516
"All we did," said the modest Dr. Malt, "was apply techniques we've known about for a long time and simply never had occasion to correlate before...The astonishing thing was not the newness of the operation but the teamwork—the way 12 doctors with expert skills, distinguished a collection of authorities as you could find anywhere, were willing to stand by and feed the incomparable extent of their knowledge to me, for no gain other than to know they had contributed."15
In April 2019, MGH received a $200 million gift from Cambridge entrepreneur Phillip "Terry" Ragon to endow a permanent vaccine research center. This gift is the largest in the hospital's history and is addition to the $100 million gift he previously gave the hospital. The center is currently testing an HIV vaccine in South Africa.17
Facilities and current operations
The main MGH campus is located at 55 Fruit Street in Boston, Massachusetts. It has expanded into an area formerly known as the West End, adjacent to the Charles River and Beacon Hill.

Controversies
In 1972 MGH received criticism from activists and legislators for their role in conducting a study of the use of amygdalotomy to reduce violence in individuals who received the procedure. This study came after significant pressure on medical practitioners to stop using invasive procedures to try to alter behavior of patients and was denounced as "a new form of lobotomy".69 Although the study was ended before any surgery was conducted on incarcerated people, MGH was simultaneously criticized for conducting genetic and fingerprint studies of people incarcerated at MCI–Cedar Junction (known as MCI–Walpole at the time), Bridgewater State Hospital, and MCI–Framingham in an attempt to discover markers for "criminal" behavior. This discredited science is often associated with attempts at the time to pathologize and incarcerate black people as a response to the Black Liberation Movement.70
In May 2015, a former MGH physician filed a lawsuit under seal alleging that at least five orthopedic surgeons endangered patient safety by keeping them under anesthesia longer than necessary while the surgeons performed simultaneous surgeries. That year, MGH fired Dr. Dennis Burke after he spoke to The Boston Globe about the dual-booking practice. In 2019, MGH paid $13 million and agreed to improve safety practices, to settle Burke's wrongful termination suit.71 Also in 2019, MGH paid $5.1 million to settle a medical malpractice lawsuit involving a concurrent surgery performed on former baseball team pitcher .
In 2022, the state approved a more than $2 billion expansion proposal from MGB, which included a $1.9 billion expansion of MGH with a new clinical building on Cambridge Street.25 This building will house 482 inpatient beds. After utilizing many of these beds to convert other parts of the hospital from 2-bed to 1-bed rooms, the hospital will net 94 new inpatient beds. The project is expected to be fully completed in 2030.26
Transportation
The closest MBTA stop to the main campus is Charles/MGH on the Red Line. On March 27, 2007, the new Charles/MGH station was opened with new renovations, including handicap accessible elevators.27 There are five main food service areas for the general public on the MGH campus. They include the Eat Street Cafe in the lower level of the Ellison Building, the Blossom Street Cafe in the Cox lobby, Coffee Central in the White lobby, Tea Leaves and Coffee Beans in the Wang Ambulatory Care Center, and Coffee South in the Yawkey outpatient center.
Though it has its own chief of psychiatry and top-ranking department, MGH is closely affiliated with nearby McLean Hospital, a psychiatric hospital also affiliated with Harvard Medical School.63
In 2012, MGH was named the number one hospital in the United States by U.S. News & World Report.
In 2011, MGH was named the second-best hospital in the United States by U.S. News & World Report. MGH consistently ranks as one of the country's top hospitals in U.S. News & World Report.66 In 2011, MGH was also ranked as one of the top three hospitals in the country for Diabetes & Endocrinology; Ear, Nose & Throat; Neurology & Neurosurgery; Ophthalmology; Orthopedics; and Psychiatry.
In August 2011, Becker's Hospital Review listed MGH as number 12 on the 100 'Top Grossing Hospitals' in America with $5.64 billion in gross revenue.67
In 2003, MGH was named the state's first Magnet hospital by the American Nurses Credentialing Center, a subsidiary of the American Nurses Association. Magnet recognition represents the highest honor awarded for nursing excellence.68
Dr. Lisa Wollman refiled her lawsuit in June 2017 under the federal False Claims Act, citing concerns that the hospital was driven by economic benefit and keeping patients unaware of the practice of concurrent surgeries. Wollman's attorney claimed that Medicare and Medicaid were being defrauded because they require that the surgeons must be present for all "critical portions" of the surgery in order to be compensated.72 MGH settled the lawsuit in 2022 for $14.9 million, including reimbursement for the disputed government payments, and agreed to get specific consent for the practice from patients.71
In June 2019, approximately 10,000 patients participating in research studies at MGH, had their names, dates of birth, diagnoses, tests, medical record numbers, and medical histories exposed in a data breach by "an unauthorized third party". The incident did not become public until August 2019.73
