History City Hospital was founded in 1837 when Cleveland City Council designated control and management of the Township Poor House to the new City Board of Health and renamed the building City Hospital. For more than a decade, the hospital operated in the two-story building, located at the northwest corner of Clinton Street (now East 14th Street) and Sumner Avenue. The site is now part of Erie Street Cemetery. In 1855, the institution, then called City Infirmary, moved to its current location about 2½ miles southwest of downtown on an 80-acre lot on Scranton Road in Brooklyn Township. The new five-story building was “designed to accommodate both the insane of the city and the sick and infirm poor, and furnish also facilities for clinical instruction to the physicians of the day." In 1889, a new building, large enough to treat 200 patients, opened on the Scranton Road campus. The building offered the latest in medical science and accommodations (steam heat, feathered pillows and hair mattresses, which replaced straw bedding). In the decades around the turn of the century, as Cleveland's population soared from 160,000 in 1880 to almost 800,000 in 1920, City Hospital saw major growth and a shift from an organization primarily serving the city's destitute to an institution providing medical care to all. It also became a robust training ground for doctors
