Massachusetts General Hospital

Massachusetts General Hospital (commonly known as Mass General or MGH) is a teaching hospital located in the West End neighborhood of Boston, Massachusetts, at 55 Fruit Street. It is the third-oldest general hospital in the United States and the first teaching hospital of Harvard Medical School. It is the original and largest clinical education and research facility of Harvard Medical School and Harvard University, and houses the world's largest hospital-based research program, with an annual research budget of more than $1.2 billion as of 2021. With more than 25,000 employees, the hospital is the largest non-governmental employer in Boston. Along with Brigham and Women's Hospital, Mass General is a founding member of Mass General Brigham, formerly known as Partners HealthCare, the largest healthcare provider in Massachusetts.

History and Founding

Massachusetts General Hospital was established in 1811 to serve Boston's general public. At that time, the sickest and most vulnerable patients were cared for in almshouses, while the wealthy could afford private care at home. Creating a general hospital was an innovative idea.

Locally, the marine hospital in Charlestown tended to the needs of sailors and the Boston Dispensary addressed the ambulatory care of paupers, but no New England facility in the early nineteenth century provided round-the-clock medical care to members of the general public. Rev. John Bartlett, Chaplain of the Almshouse in Boston, dreamed of establishing such a hospital, which would make state-of-the-art medical care available to the physically or mentally ill while affording improved opportunities for practical medical education. He joined with like-minded doctors and leading citizens to organize a fundraising campaign. Dr. James Jackson and Dr. John Collins Warren were among the foremost proponents of this plan.

On August 20, 1810, Boston physicians Drs. James Jackson and John Collins Warren issued a "circular letter" inviting contributions for the funding of a hospital, and in February 1811, a charter of incorporation was granted by the Massachusetts Legislature. Fundraising began, although it was protracted due to the War of 1812 and the financial Panic of 1819. Donations ranged from $.25 to $20,000, and included such unusual gifts as a 273-pound sow.

The War of 1812 delayed fundraising for several years, but in 1816 the Trustees of Massachusetts General Hospital bought and renovated an estate in Charlestown. This institution split off from the general hospital and was focused solely on patients with mental health disorders. This facility became McLean Asylum, now McLean Hospital in Belmont.

The following year, a four-acre field in Boston's West End known as Prince's Pasture was acquired for construction of Massachusetts General Hospital. The building was designed by Charles Bulfinch, the first American-born architect who also designed many other buildings in the West End. The Trustees of the Hospital purchased the land on Prince's Pasture in 1817, and the Bulfinch building's cornerstone was laid on July 4, 1818. On September 1, 1821, the hospital admitted its first patient into the building that had been designed by Boston architect Charles Bulfinch.

MGH 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.

The Bulfinch Building

The Bulfinch Building remains one of the most architecturally significant hospital structures in the United States. The Bulfinch Building, named after its architect Charles Bulfinch, opened to patients in 1821 and was hailed for its modern, innovative construction. The 36,000-square-foot Greek Revival-style building was made of granite and featured windows on all sides, as well as central heating and rudimentary indoor plumbing.

It was designed by architect Charles Bulfinch and built between 1818 and 1823, with a major expansion in 1844–46. A National Historic Landmark, it is an excellent example of Classical Revival architecture and a rare surviving example of an early 19th-century public hospital building. The entire building was listed on the National Register of Historic Places and designated a National Historic Landmark in 1970, as an excellent example of Classical Revival architecture and as one of the oldest public hospital buildings in the nation.

Charles Bulfinch (1763–1844), who was born in Boston and educated at Harvard, was also the first American-born professional architect. When Bulfinch visited Europe from 1785–1787, he was influenced by the classical architecture in Italy and the neoclassical architecture in England. Months after beginning work on the hospital, President James Madison called Bulfinch to Washington, D.C., to redesign the U.S. Capitol. He left MGH in the hands of his assistant, Alexander Parris, who oversaw work on the building that would bear his mentor's name.

Massachusetts General Hospital celebrated the 200th anniversary of the opening of the Bulfinch Building in 2021. The first patient on September 1, 1821, was a horse saddler with syphilis. Hospital staff and descendants of the building's architect Charles Bulfinch were on hand to unveil banners and celebrate the occasion.

The Ether Dome and Medical Milestones

Among the most celebrated moments in MGH's history—and in the history of medicine—is the first public demonstration of surgical anesthesia, which took place inside the hospital's operating amphitheater on October 16, 1846. In the autumn of 1846, three men made history inside the surgical amphitheater in Massachusetts General Hospital's Bulfinch Building. Dentist William T.G. Morton administered ether to a patient named Edward G. Abbott, who had a tumor of the jaw. When Abbott slipped into unconsciousness, surgeon John Collins Warren, MD, bent over his patient and began removing the tumor. To the audience's amazement, Abbott never cried out in pain during the procedure. For the first time in public, a physician had performed a surgical procedure using ether as an anesthetic. The event ushered in the era of pain-free surgery, and the hospital's amphitheater would be known forever as the Ether Dome.

The operating room came to be known as "The Ether Dome," and in 1965 was registered as a National Historic Landmark. The Ether Dome is still accessible to the public, though it now serves as a lecture hall rather than an operating theater.

Beyond the landmark anesthesia demonstration, MGH has been the site of numerous other medical advances. These include the identification of appendicitis by Dr. Reginald Fitz (1886), the establishment of the first medical social service by Dr. Richard Cabot and Ida Cannon (1905), and the first replantation of a severed arm by a surgical team — the last of which cemented MGH's reputation as a center for surgical innovation. The original domed operating amphitheater, where anesthesia was first publicly demonstrated in 1846, is now a Registered National Historic Landmark. MGH has achieved countless medical milestones, including the first successful reattachment of a human limb.

The date of the first operation at MGH, October 16, is celebrated annually in Boston as Ether Day, and around the world as World Anesthesia Day.

Research and Academic Mission

Mass General operates the most generously funded hospital-based research enterprise in the United States. With over 1,200 clinical trials taking place at any given time, Mass General conducts the largest hospital-based research program in the United States. Annual research operations total over $1 billion, and Mass General comprises more than 9,500 researchers working across more than 30 institutes, centers, and departments.

Massachusetts General Hospital received $655 million in funding from the National Institutes of Health in fiscal year 2024 — a slight decrease from the $675 million it secured in 2023, yet it remained the most-awarded hospital in the U.S. Six of the top 20 recipients are located in the Boston area, and nearly one-third specialize in pediatric or cancer care, highlighting where federal research priorities and capacity are concentrated.

As a founding member of Mass General Brigham, Massachusetts General Hospital is the original and largest teaching hospital of Harvard Medical School, where nearly all Mass General staff physicians serve on the faculty. Each year, Mass General is named by U.S. News & World Report as one of America's top hospitals and is the only U.S. hospital to be ranked in all medical specialties.

MGH is nationally ranked in 14 adult specialties and rated high performing in 23 adult procedures and conditions, including top ratings such as Abdominal Aortic Aneurysm Repair, Aortic Valve Surgery, Back Surgery (Spinal Fusion), Chronic Obstructive Pulmonary Disease (COPD), and Colon Cancer Surgery.

The Mass General Cancer Center was formally established in 1989 as an independent aspect of the Mass General Hospital system. The center was one of only 53 locations to receive the designation as a National Cancer Institute Comprehensive Cancer Center.

Hospital Operations and Campus

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. The hospital handles around 1.5 million outpatient visits each year at its main campus, as well as its seven satellite facilities in Boston at Back Bay, Charlestown, Chelsea, Everett, Revere, Waltham, and Danvers.

The hospital has 1,011 beds and admits around 50,000 patients each year. The surgical staff performs over 34,000 operations yearly. The obstetrics service handles over 3,800 births each year. The Massachusetts General Hospital Trauma Center is the oldest and largest American College of Surgeons-verified Level One Trauma Center in New England, evaluating and treating over 2,600 trauma patients per year.

Massachusetts General Hospital for Children (MGHfC) is a pediatric acute care children's teaching hospital located in Boston, Massachusetts. The hospital has an estimated 100 pediatric beds and is affiliated with Harvard Medical School. The hospital is a member of Mass General Brigham and is the only children's hospital in the network. The hospital provides comprehensive pediatric specialties and subspecialties to patients aged 0–21 throughout Boston and the wider Massachusetts.

Mass General Brigham System

Massachusetts General Hospital and Brigham and Women's Hospital created a new parent corporation, Partners HealthCare, in 1994 amid industry pressure to coordinate care, negotiate with payers, and control costs. Following formation, Partners expanded across eastern Massachusetts via affiliations with community and specialty hospitals. North Shore Medical Center (now Salem Hospital) became the first community member in 1996; Faulkner Hospital merged with Brigham and Women's in 1998; and Newton-Wellesley Hospital joined in 1999.

In November 2019, Partners announced a five-year strategy and said it would rebrand as Mass General Brigham to present a unified identity across the system. As of fiscal 2024, MGB reported about US$20.6 billion in operating revenue and a return to positive operating margin after pandemic-era losses. With roughly 82,000 employees, it has been described as the state's largest private employer.

Mass General Brigham's history is built on New England hospitals founded over 200 years ago, some of the first and most prestigious hospitals in the world as well as the oldest and largest teaching affiliates of Harvard Medical School. Today, Mass General Brigham comprises 16 member institutions, including its founding members Massachusetts General Hospital and Brigham and Women's Hospital.
