In the early 1970s, Henry J. Heimlich, MD, developed a first aid technique for choking, known as the Heimlich maneuver. Dr. Heimlich developed this tool, also called abdominal thrusts, after reading an article about accidental deaths. He was shocked to learn that choking was a leading cause of death, especially in children under 3 years of age.
He even used his maneuver himself. At age 96, Dr. Heimlich used this technique on a fellow diner at his home, saving the life of an 87-year-old woman who was choking.
