A LIFELONG CURIOSITY: Reflections on a Life in Medicine

From a child tinkering with batteries and barn wire to a physician at the forefront of cardiac innovation, Otto Kahn, M.D., has spent more than half a century asking the same essential question:
How does it work — and how can we make it better?

In this deeply personal memoir, Dr. Kahn invites readers into a remarkable era of discovery. With clarity, warmth, and a touch of humor, he reveals what it was like to witness — and at times help shape — breakthroughs in pacing, mechanical circulatory support, open-heart surgery, and transplantation. His stories capture the excitement of medicine at its turning points and the wonder of watching new ideas take flight.

At its heart, this book is about more than scientific progress. It celebrates curiosity — the questions that spark insight, the persistence that drives discovery, and the human connections that give every advance meaning. Dr. Kahn introduces the mentors who inspired him, the colleagues who challenged him, and the patients whose trust shaped his life’s work.

For readers drawn to science, medicine, or the spirit of possibility, this memoir offers an intimate look at a field still evolving — and a reminder that every breakthrough begins with curiosity.
