The story

Founded by George Washington Crile in 1921.1

Beginnings

The organization grew out of the surgical practice of Frank J. Weed (died 1891) at 16 Church Street on the near-west side of Cleveland. The practice was purchased by his two assistants, Frank E. Bunts and George Washington Crile. In 1892 they were joined by Crile's cousin, William E. Lower, and in 1897 the practice moved to the Osborn Building on Prospect Avenue, downtown Cleveland.

A four-story outpatient building was constructed, and Cleveland Clinic was dedicated at a private ceremony on February 26, 1921. It opened its doors two days later to the public and registered 42 patients. By April 1921, it had 60 employees, including 14 physicians and four nurses. In 1922 the founders purchased four private homes nearby for hospitalization, radiation treatment, and administration. A fifth house was acquired as a residence for patients with diabetes receiving insulin treatments. To meet rising patient volume, a 184-bed hospital was built in 1924, located at East 90th Street and Carnegie Avenue. A power plant, laundry, and ice plant were also built. A research laboratory was constructed in 1928.

Cleveland Clinic fire

On May 15, 1929, nitrocellulose x-ray films stored in the basement of the outpatient building ignited. An explosion sent a cloud of toxic oxides of nitrogen and carbon though the building. One hundred and twenty-three people, including John Phillips, one of the founders, lost their lives. A dozen investigating agencies were not able to determine what had caused the fire. Cleveland Clinic's own inquiry narrowed the possible causes down to spontaneous combustion caused by heat; a discarded cigarette or match; and contact with an extension cord light hung over a stack of films.

Philanthropist Samuel Livingston Mather II formed a committee of 36 community leaders to help Cleveland Clinic reestablish itself in temporary quarters across the street. Patient care services resumed five days later. The 1921 building was completely renovated, and a new three-story clinic building, with a new main entrance, was added in 1931. All debts were repaid by 1941.

Growth of specialization

Cleveland Clinic built new operating rooms in the early 1970s to accommodate the growth of cardiac surgery. The Martha Holden Jennings Education Building opened in 1964, with an auditorium named for Dr. Bunts. A new hospital building (currently home to Cleveland Clinic Children's Hospital) opened in 1966, and a research building opened in 1974 (demolished in 2007). A pathology and laboratory medicine building was constructed on Carnegie Avenue in 1980.

William S. Kiser, chairman of the board 1977–1989, led the development of a strategic plan to accommodate growing patient volumes in the late 1970s. This resulted in a group of buildings known as the Century Project. Completed in 1985, the Century Project includes a 14-story outpatient building (now known as the Crile Building) designed by architect Cesar Pelli.

In September 2014, the Cleveland Clinic opened the center for Functional Medicine, directed by Mark Hyman. Other alternative medicine offerings at the Cleveland Clinic, such as reiki and hypnotherapy, came under controversy in 2017 after a then-Cleveland Clinic physician published an anti-vaccine article. then-CEO Toby Cosgrove stated that this was in response to patients who "want more than conventional medicine can offer." Nonetheless, shortly afterward, the hospital stopped selling some homeopathic products and discontinued online sales of wellness products.

In 2026, under threat from the Trump administration Department of Justice, the Cleveland Clinic agreed to open the nation's second "detransition clinic" for those who had previously received transgender healthcare - this development shortly following a similar arrangement involving Texas Children's Hospital.

Research and education

The Cleveland Clinic Lerner Research Institute (LRI) conducts biomedical research in a 480,000-square-foot building that opened in 1999, following a $16 million donation from Al and Norma Lerner in 1997, the largest single charitable donation made to the Cleveland Clinic up until that point. LRI hosts graduate student research through joint PhD programs in conjunction with nearby universities, including Case Western Reserve University, Cleveland State University (including an NIH-funded PhD program for minority and underrepresented students in science, technology, engineering, and mathematics), Kent State University and the University of Akron.

In 2002, the Lerners eclipsed their previous gift and made a $100 million donation to establish the Cleveland Clinic Lerner College of Medicine (CCLCM) within Case Western Reserve University School of Medicine, opening in 2004. Physician researcher Eric Topol played an important role in securing the donation from the Lerner family. Topol served as Provost and Chief Academic Officer at CCLCM until 2006, when his position was eliminated amid controversy regarding his criticism of Vioxx and disagreements with other Cleveland Clinic leaders, including then-CEO Toby Cosgrove. CCLCM is a five-year medical school program affiliated with the Case Western Reserve University School of Medicine with 32 students per class, each receiving a scholarship for full tuition and fees. While traditional MD-granting medical schools in the U.S. are four-year programs, the extra year in the program is dedicated to a year of research. The curriculum is notable for its lack of class rank, pre-clinical or clinical grading, or end-of-course examinations.

In 2019, Cleveland Clinic and Case Western opened the Samson Pavilion Health Education Campus on the campus of the Cleveland Clinic, a $515 million building project, amid a multi-million dollar joint fundraising campaign between CWRU and the Cleveland Clinic. The campus houses students Case Western Reserve School of Medicine (CCLCM and traditional MD programs), Frances Payne Bolton School of Nursing and Case School of Dental Medicine, all of which—with the exception of CCLCM—had previously held classes on the campus of CWRU and University Hospitals Cleveland Medical Center. The move, announced in 2013, was a major contributing factor for University Hospitals to shift its name from University Hospitals Case Medical Center to University Hospitals Cleveland Medical Center in 2016, as well as renegotiate its affiliation agreement with CWRU that same year.

Cleveland Clinic publishes the peer-reviewed Cleveland Clinic Journal of Medicine monthly, focusing on internal medicine, endocrinology, and diabetes.
