Review

Early life and education

The roots of the Mayo Clinic trace back to Dr. William Worrall Mayo [1], a British immigrant who settled in Rochester, Minnesota, in 1863. He was a general practitioner who also served as an examining physician for the US Army recruitment board. His medical practice and principles laid the foundation for the Mayo Clinic and the Mayo way of delivering care. William James Mayo ("Will"), born in 1861, and Charles Horace Mayo ("Charlie"), born in 1865, were heavily influenced by their father's dedication to medicine (Figure 1) [2]. Starting at an early age, the Mayo brothers assisted their father's medical practice, compounding pills and solutions prescribed to patients and performing other basic patient care tasks. These early days played a critical role in shaping their approach to medicine. Growing up in a household deeply engaged with medical practice with their father's emphasis on practical medicine, they were exposed to hands-on learning from a young age. This, combined with formal medical education at prestigious institutions like the University of Michigan (Will) and the Chicago Medical College (Charlie), laid the foundation for their later innovations [2]. These formative experiences fostered their understanding of the importance of surgical precision and patient-centered care, which became hallmarks of their approach to surgery and the development of integrated medical care.

Founding of the Mayo Clinic

On August 21, 1883, Rochester, Minnesota, was impacted by a tornado, leaving widespread destruction in a major part of the city. Temporary facilities staffed by physicians and other medical staff cared for the wounded. The Sisters of St. Francis, whose primary role was in school education, rose to the occasion and volunteered their help in the event of the disaster. Mother Alfred Moes partnered with Dr. William Worrall Mayo and his sons. The sisters proposed setting up a medical facility, managing it, and training future nurses with the Mayo family in charge of patient care [2].

Saint Mary's Hospital was founded in 1889 (Figure 2) [3] and marked the beginning of what would evolve into the Mayo Clinic [4]. As a collaborative effort between the Mayo family and the Sisters of St. Francis, the hospital was created in the aftermath of a natural disaster but driven by a vision to provide continued high-quality medical care. This collaboration between physicians and the religious community set the stage for developing a unique, team-based approach to healthcare. Patient care was prioritized, and physicians, nurses, and administrators worked together toward a common goal. This cooperative spirit would later become a defining feature of the Mayo Clinic's structure, fostering an environment where innovation, teamwork, and patient-centered care thrived. The success of Saint Mary's Hospital laid the groundwork for the Mayo Clinic's eventual transformation into a world-renowned medical institution [4].

Innovations and contributions

The Mayo Clinic's success can be attributed to the brothers' relentless pursuit of innovation. Will and Charlie Mayo were talented surgeons who also traveled to learn new techniques and protocols from other surgical practices to improve patient care [5]. They visited the Johns Hopkins Hospital and trained under renowned surgeon William Halsted, where they were introduced to the antiseptic techniques developed by Joseph Lister [6], which they brought back to Rochester. From its inception, Saint Mary's Hospital was one of the first centers worldwide to employ the new principles of disinfection and antiseptic practices. By meticulously preventing infections, they improved surgical outcomes and reduced mortality.

Will Mayo specialized in abdominal and pelvic surgeries, while Charlie Mayo leaned toward head, neck, and neurological surgeries. Their meticulous approach to surgical procedures and emphasis on sterile techniques and postoperative care set new benchmarks in the field. The Mayo brothers introduced pioneering surgical methods that significantly improved patient outcomes [5]. They also introduced novel methods in thyroid surgery and developed pioneering approaches to gallbladder and gastric surgeries [7]. They were also early adopters of X-ray technology, recognizing its potential in diagnostics and treatment planning [8]. The collaborative, multidisciplinary nature of the Mayo Clinic allowed for the continuous refinement of these techniques, with surgeons sharing knowledge in real time, something rare for the era. As their popularity surged due to the superior results of their surgeries at Saint Mary's Hospital, more patients came to them. The referring physicians used the term "The Mayo Clinic," but the name was not formalized until 1914 [2]. The medical community highly regarded their work, receiving praise at national and international surgical conferences. These innovations not only advanced the field of surgery but also positioned the Mayo Clinic as a leader in medical education and research.

Impact on medical education

The Mayo brothers' contributions to medical education were transformative. They recognized the need for structured training programs to produce competent, skilled physicians. In the words of Dr. Charles Mayo, "There are two objects of medical education: to heal the sick and to advance the science" [9]. One of their most lasting contributions was their belief in the value of hands-on training under the supervision of experienced physicians, an approach that became the cornerstone of the residency system [10]. This model became the gold standard for medical training, influencing institutions worldwide. The three-year physician training programs were started in 1915 in partnership with the University of Minnesota [11]. The first Ph.D. in biochemistry was conferred in 1917. While the degrees in earlier years were granted with the University of Minnesota affiliation, the Mayo Clinic began to award master's and Ph.D. degrees independently in 1989 [11].

The Mayo Clinic became a hub for medical education, attracting physicians from around the world, including Europe and Asia. The brothers emphasized the importance of continuous learning and professional development, establishing residency programs, and fostering an environment of academic excellence. They developed structured educational programs that combined clinical practice with research, allowing physicians to continually refine their skills while staying current with medical advancements. This model directly influenced the development of modern postgraduate medical education, with many of today's residency programs mirroring the comprehensive, interdisciplinary approach the Mayo brothers pioneered. Their commitment to lifelong learning persists in today's continuing medical education requirements, ensuring that physicians stay current on the latest practices. The Mayo Clinic remains a leader in medical education, with its residency and fellowship programs setting the standards for medical education globally. Their commitment to education extended to publishing extensively in medical journals, contributing to the body of medical knowledge, and setting standards for clinical practice. Their emphasis on continuous education ensured that physicians remained abreast of the latest medical advancements.

Will Mayo served as a colonel for the US Army Medical Corps in World War I and was a chief advisor in the Surgeon General's office [15]. Charlie Mayo was a colonel involved in the surgical care of the soldiers as an associate chief advisor. Later, they both served in the National Defense Council's General Medical Board. The Mayo Clinic played a significant role in the background of World War I [16]. Will and Charlie organized educational camps to train military doctors in the latest medical and surgical techniques. Despite their commitments to the Army, they ensured that one of them was always available at the Mayo Clinic for its patients. After the war ended in November 1918, both Mayo brothers were promoted in the US Army Reserve to the rank of brigadier general. They also received the United States Distinguished Service Medal as an appreciation for their service to the country during the crucial wartime [17]. Their wartime experiences dealing with large-scale injuries and complex surgeries directly influenced their post-war medical practice, driving further innovation in trauma care. The Mayo Clinic's Military Medicine Program [18] was developed to better understand and address the unique needs of service members on and off the battlefield. It serves as a center stage for Mayo Clinic researchers and potential collaborators interested in military and defense-related research initiatives.
