Since its adoption as a first aid method, the Heimlich Manoeuvre has saved untold numbers of lives around the world. Developed by American physician Dr Henry Heimlich as a way to save choking victims from dying, his manoeuvre would become famous just weeks after it was written about in a medical journal. But as well as his namesake manoeuvre, Heimlich was responsible for several other medical innovations throughout his life. Ashley Byrne hears from Janet Heimlich, one of Dr Heimlich's children.
