context_page_description: The Cleveland Clinic was established in 1921 as a group surgical-medical practice with its own dedicated hospital in Cleveland, in the U.S. state of Ohio.
context_section_description: The four purchased land at the corner of Euclid Avenue and E. 93rd St in Cleveland and constructed a four-story building with facilities for outpatient clinics and inpatient hospitalization, along with a medical laboratory. The building, which still stands and is still used as part of the Clinic's mission, was dedicated at a private ceremony on February 26, 1921. William Benson Mayo, MD, of the Mayo Clinic, delivered the main address. On February 28, 1921, Cleveland Clinic opened its doors to the public and registered 42 patients. In April 1921, Cleveland Clinic had 60 employees, including 14 physicians, four nurses, a telephone operator, six cleaners, 22 clerical workers, an art department, and an unknown number of laboratory technicians.
  In 1922, the founders purchased four private homes nearby used 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.
