Mayo Clinic’s legacy of excellence stems from its pioneering multispecialty group practice model, patient-first philosophy, and over 150 documented contributions to medicine spanning 160 years. Founded amid a 1883 tornado’s devastation in Rochester, Minnesota, it evolved from a family practice into a global benchmark for integrated care, research, and education.
Origins and Foundational Philosophy
William Worrall Mayo established a solo practice in Rochester in 1864, later joined by sons William James (Dr. Will) and Charles Horace (Dr. Charlie) Mayo. The 1883 tornado, injuring over 200, prompted collaboration with the Sisters of St. Francis, leading to Saint Mary’s Hospital in 1889—a handshake agreement blending medical expertise with nursing care. This crisis forged the “needs of the patient come first” ethos, codified as RICH TIES (Respect, Integrity, Compassion, Healing, Teamwork, Innovation, Excellence, Stewardship).
Henry Plummer revolutionized organization by inventing the integrated medical record in the early 1900s, enabling seamless specialist collaboration and reducing errors— a system still foundational today. The brothers donated their savings in 1919 to create a nonprofit, ensuring reinvestment in mission over profit. This model attracted pioneers like Augustus Stinchfield and E. Star Judd, expanding into a group practice that redefined medicine.
Pioneering the Group Practice Model
Mayo Clinic invented the integrated multispecialty group practice in 1914 with its “red brick” building, designed for fluid patient-staff movement across specialties. Unlike solo practices, physicians shared records and consulted freely, fostering efficiency for complex cases. The 1928 Plummer Building enhanced this, featuring steam sterilization, pneumatic tubes, and knee-operated sinks—innovations by Plummer himself.
This approach influenced global healthcare; a 1906 Canadian surgeon noted its specialization-cooperation motto as replicable elsewhere. By prioritizing teamwork, Mayo handled tertiary care for patients nationwide via railroads, setting precedents for modern health systems. Its nonprofit alignment with education and research, formalized in 1915 via the Mayo Foundation, embedded learning in practice.youtube
Surgical and Diagnostic Breakthroughs
Mayo advanced frozen-section biopsy in 1905, allowing intraoperative cancer diagnosis by Louis Wilson, enabling precise excisions. Albert Broders created the first tumor-grading index in the 1920s, standardizing severity assessments worldwide. The Mayo stand, a one-legged mobile instrument table, became ubiquitous in operating rooms.
In 1935, Mayo opened the first U.S. hospital-based blood bank, revolutionizing transfusions. Edward Kendall isolated thyroxine in the 1910s, advancing thyroid treatments. During WWII, a secret team developed the G-suit with air bladders to counter pilot blackouts, charging $1 yearly to the U.S. government. The BLB oxygen mask by Boothby, Lovelace, and Bulbulian enabled high-altitude flight
Open-heart surgery milestones included refining the Gibbon heart-lung machine into the Mayo-Gibbon version for the world’s first successful series. Mark Coventry performed the first FDA-approved total hip replacement in 1969, launching joint arthroplasty. Pioneering postoperative ICUs ensured advanced monitoring post-surgery
Nobel Prizes and Pharmacological Advances
Two Mayo researchers, Edward Kendall and Philip Hench, shared the 1950 Nobel Prize in Physiology or Medicine for discovering cortisone’s arthritis-relieving effects, alongside Tadeus Reichstein. Kendall, Mayo’s first rheumatologist, and Hench identified adrenal cortex hormones, transforming treatments for inflammatory diseases. This bench-to-bedside triumph exemplified Mayo’s translational ethos.
Russell Wilder validated insulin dosing and safety, among the first to apply it for diabetes control. The ketogenic diet for epilepsy emerged here, alongside histamine tests for pheochromocytoma and sodium nitroprusside for hypertension. Prednisone became standard for polyarteritis, once fatal
Technological and Imaging Milestones
Mayo introduced North America’s first CT scanner in 1973 after Dr. Hillier Baker’s on-site purchase in London. Rapid PCR assays amplified DNA for diagnostics, revolutionizing disease detection. Post-2001 anthrax attacks, a DNA test detected trace amounts swiftly. A strep A test yielded results in two hours.
Proton beam therapy treated over 10,000 patients by 2023, comprising 2% of U.S. radiation cases. MR-guided focused ultrasound offered nonsurgical uterine fibroid treatment. FISH techniques advanced genetic analysis. C-11 Choline PET imaging gained FDA approval for prostate cancer recurrence.
Research and Regenerative Medicine
Mayo invests over $660 million annually, yielding 9,275 peer-reviewed papers with 5,500 researchers. The Center for Innovation, since 2008, drives 270+ projects, including 3D organ printing and AI diagnostics. Regenerative trials use patient cells for heart repair; spinal cord stimulation restored partial mobility in a paralyzed patient.
The Well Living Lab studies environment-health links; partnerships with Apple (HealthKit) and Google integrate 15,000 devices. mTOR discovery spurred drug-eluting stents. During COVID-19, Mayo led convalescent plasma programs and Advanced Care at Home virtual models.

Educational Legacy
The Mayo Foundation, endowed in 1915 with $1.5 million, launched graduate training aligned with practice. Mayo Clinic Alix School of Medicine ranks top-15, training via 300+ residencies for 1,791 trainees across five schools. This embeds education in care, producing leaders like AMA presidents.
The Mayo Clinic Care Network shares protocols globally; international sites in London and UAE extend reach.
Architectural and Cultural Icons
Iconic buildings like the Gonda (2001) and Opus Imaging (2007) house advanced facilities; bronze Plummer doors close for historic events. An extensive art collection—Warhol, Rodin, Calder—links arts to healing. The 150th anniversary compiled 150 milestones, underscoring enduring impact.youtube
Enduring Global Influence
Mayo serves 1.3 million patients from 138 countries yearly, topping U.S. News Honor Rolls for decades. Its model inspires systems worldwide, balancing innovation with compassion. As CEO Gianrico Farrugia leads, expansions like Discovery Square sustain the legacy.
Challenges like 2023 lobbying persist, but rankings—No. 1 Newsweek seven years running—affirm excellence. Mayo’s handshake-born covenant endures, proving patient needs first yields timeless progress.
