The birth of Mayo Clinic Laboratories: From tiny operation to international mainstay

 As the 1960s rolled into 1970, the country was in a recession and the Vietnam War showed no signs of ending. Rock icons Janis Joplin and Jimi Hendrix both died that year. Gross Domestic Product fell while inflation rose. Plus, interest rates soared to help pay for deficit spending on the war. Meanwhile, Mayo Clinic’s Board of Governors was considering new ways to bring in revenue. So on March 17, 1971, after much investigation, hesitation, and deliberation, the Regional Laboratory was founded. For the first time in Mayo Clinic’s history, the institution would get involved with the community practice of pathology to serve outside patients in the region and beyond. Before this, Mayo was entirely an academic institution, serving only its own patients. The funds from this new lab would be used for research and education.
