Robert L. Frye, MD, a beloved cardiologist who influenced entire generations of clinicians, died Aug. 4. He was 94 years old.

Frye spent more than 60 years with Mayo Clinic and served as the president of the American College of Cardiology (ACC) in 1991-1992. He also served in a variety of other leadership positions with ACC.

Before landing at Mayo Clinic, Frye completed his residency at Johns Hopkins Hospital and became the first physician research fellow and clinical associate at the National Institutes of Health (NIH). He was recruited for that position by Eugene Braunwald, MD, considered by many to be the “father of modern cardiology.”

“Dr. Frye holds a unique place in the history of cardiovascular medicine,” Valentin Fuster, MD, PhD, president of Mount Sinai Fuster Heart Hospital and physician-in-chief of The Mount Sinai Hospital, said in an ACC statement. “As the first Braunwald Fellow at the NIH, he helped lay the foundation for a generation of clinical discovery that transformed our field. Beyond his scientific contributions, Dr. Frye was deeply admired and loved by all of us who had the privilege of working with him. His intellect, collegiality and unwavering commitment to patients and science leave a lasting legacy that continues to inspire us all.”

“For so many at Mayo Clinic, including me, Dr. Frye represented the very best of who we strive to be,” added Sharonne N. Hayes, MD, a cardiologist and professor of cardiovascular medicine with Mayo Clinic. “He led with humility, kindness, purpose and an unwavering focus on the needs of patients. Those of us who had the privilege of working with him during his more than 60 years at Mayo Clinic, will remember not only his brilliance and accomplishments, but also the warmth, compassion and quiet steadiness he brought to every interaction. He inspired by example – an example that reminds us that meaningful work is made even more powerful when it is carried out with humanity, generosity and a deep commitment to others.”

ACC President Roxana Mehran, MD, director of interventional cardiovascular research and clinical trials at the Zena and Michael A. Wiener Cardiovascular Institute at the Icahn School of Medicine at Mount Sinai, also reflected on Frye’s decades-long impact on cardiovascular medicine.

“Dr. Frye's legacy lives on through the discoveries he advanced, the physicians he mentored and the profession he helped lead,” she said. “He belonged to a pioneering generation of cardiovascular physicians whose work transformed the diagnosis and treatment of heart disease, benefiting millions of patients around the world. The ACC extends its deepest condolences to his family, friends, colleagues, former trainees and all who were privileged to know him.”
