Learn how a Polish monk created the first bulletproof vest and, in doing so, changed the world.

In 1897, at a public demonstration in Chicago, a man accomplished the unprecedented and seemingly physics-defying feat of stopping a bullet. After being shot with a revolver at close-range, and temporarily falling to the ground, the man was completely unscathed. That man, Kazimierz Żegleń, had succeeded in creating a vest that made him bulletproof.

In this episode, our hosts John and Lea discuss the man behind the vest, Kazimierz Żegleń, and the story of its creation. Who was Żegleń in the first place? How was he inspired to create a potentially life-saving vest and how did he manage to invent it? What was the immediate impact of this supposedly bulletproof vest? Did it save any lives? And finally, how has Żegleń’s invention influenced modern-day bulletproof vests?

Sławomir Łotysz / professor at the Institute of the History of Science at the Polish Academy of Sciences, Warsaw. Professor Łotysz kindly agreed to tell us the story of Kazimierz Żegleń, as well as provide us with lots of materials on Żegleń's inventions and biography. Professor Łotysz's research was made possible largely thanks to the generous support of the Chemical Heritage Foundation of Philadelphia.
