The Greatest Doctors

One surgeon. One dying patient. One impossible operation that changed medicine forever.

On December 3, 1967, Dr. Christiaan Barnard did the unthinkable: he transplanted a human heart into another person's chest. The patient survived just 18 days, but his beating heart launched a medical revolution.

Why was Barnard the first when so many brilliant surgeons were racing toward the same breakthrough? Was it genius, preparation, teamwork, or simply the courage to take a risk no one else would?

In this gripping episode of The Greatest Doctors, Dr. Andrew Zimmerman takes you inside the historic operation in Cape Town, drawing on his exclusive interviews with two leading cardiac surgeons from the University of Cape Town.

Discover the untold story of Hamilton Naki, a gardener who became a remarkable surgical researcher, the extraordinary team behind Barnard's success, and the lessons that continue to shape medicine nearly 60 years later.

Because sometimes, changing the world isn't about knowing what others don't. It's about having the courage to do what others won't.

How to Get Healthcare Ideas Funded- What doctors can learn from business

Why were women safer giving birth with midwives than with doctors?

In 1840s Vienna, Ignaz Semmelweis uncovered a horrifying answer: doctors themselves were carrying deadly infection from the autopsy room to the maternity ward.

His solution was astonishingly simple—wash your hands.

But being right wasn’t enough.

In Episode 2 of The Greatest Doctors, Dr. Andrew Zimmerman travels to Vienna to trace Semmelweis’s story firsthand, including conversations with medical historian Dr. Bernhard Leitner, Austria guide Marieta Teich, and Johannes Culen of the Semmelweis Foundation.

It’s a story of discovery, resistance, institutional politics, passion, and the tragic consequences of having the truth but struggling to persuade others to listen.

Plus: what Semmelweis taught me about advocating for my own patients when the healthcare system gets in the way.

The science has changed. The human problem hasn’t.
