CLEVELAND -- The Cleveland Clinic Foundation is celebrating its 92nd anniversary this year.

It was founded in Februiary 1921 by four doctors with several goals in mind:

  • Medical care
  • Research
  • Innovation
  • Doctor education

Records show that three of the four founders had served together in a U.S. Army medical unit in France during World War I.

The Cleveland Clinic Disaster of 1929 -- a basement fire caused by combustible x-ray film that left 123 dead -- was a tragedy that temporarily set back the hospital's progress.

After World War II,the Cleveland Clinic rose to become one of the nation's leading medical centers. During the '40s and '50s, Clinic researchers pioneered dialysis and kidney treatment and were the first to identify carpal tunnel syndrome and isolate the neurotransmitter serotonin.

By 1960, the Cleveland Clinic had also become a national leader in cardiac care. Clinic physicians performed the first coronary angiography in 1958 and continued to be pioneers in the field of heart surgery in the proceeding decades.

The Clinic's main campus, onEuclid Avenue,has undergone tremendous growth and expansion since the '70s. largest private employers.
