The techniques that save lives from cardiac arrest today — CPR, defibrillation, the AED on the wall of your local sports centre — did not emerge fully formed. They are the product of decades of painstaking research, clinical courage, and the work of a small number of extraordinary individuals who refused to accept that a stopped heart was always the end.
This section profiles the pioneers who built the foundations of modern resuscitation science, and takes a look at the long, colourful, and occasionally baffling history of what came before them.
Before Modern Resuscitation
Before Modern Resuscitation — From ancient Egyptian incantations to the tobacco smoke enema, humanity spent thousands of years trying to bring the dead back to life before anyone got close to the right answer. A brief and occasionally humbling look at what came before CPR.
The Pioneers
Frank Pantridge (1916–2004) — The Belfast cardiologist who invented the portable defibrillator and created the world’s first mobile coronary care unit, taking resuscitation out of the hospital and onto the street. His “Pantridge Plan” was adopted by emergency services worldwide and is the direct ancestor of every AED in public use today. A former prisoner of war on the Burma Railway, his life was as extraordinary as his science.
James Elam (1918–1995) — The American physician who proved that exhaled air was a viable resuscitative gas — the insight that made mouth-to-mouth resuscitation possible. Working with Peter Safar under US Army funding, Elam co-developed CPR and helped produce the Resusci Anne mannequin that has trained millions of people worldwide to save lives.
Peter Safar (1924–2003) — The Czech-American anaesthesiologist known as the father of modern CPR. Safar created the A-B-C resuscitation framework that the American Heart Association adopted as the global standard, founded the world’s first multidisciplinary intensive care unit, and persuaded Åsmund Laërdal to create the Resusci Anne training mannequin. His later research into therapeutic hypothermia after cardiac arrest shaped modern post-resuscitation care.
Paul M. Zoll (1911–1999) — The Harvard cardiologist who pioneered external cardiac pacing and defibrillation, demonstrating in 1952 that electrical shocks delivered through the chest wall could restart a stopped heart. He later co-founded ZOLL Medical Corporation, whose equipment is used by emergency services around the world.
Douglas Chamberlain (1931–2025) — The Brighton cardiologist who founded the first paramedic unit in Europe and brought defibrillation to UK ambulance crews. A co-founder of both the Resuscitation Council UK and the European Resuscitation Council, and co-chair of ILCOR from its founding in 1992. Described by the College of Paramedics as “the grandfather of paramedicine”, he died in May 2025 at the age of 94. Paul Swindell had the privilege of interviewing him for the Life After Cardiac Arrest podcast in 2019.
Why This History Matters
For those of us who survived a cardiac arrest, this history is personal. The defibrillator that restarted your heart, the CPR that kept your brain alive until help arrived, the paramedic who appeared within minutes — all of it traces back to the work of these pioneers and the many others who built on their foundations.
Survival rates from out-of-hospital cardiac arrest remain stubbornly low. The history of resuscitation is also a reminder of how much further there is still to go — and why the work of organisations like SCA UK, advocating for better survivorship support and continued research, matters so much.
