Barnes Wallis is best known as the English inventor and scientist who designed and invented the bouncing bomb for the “Dambusters” raid of May 1943. Trained as a marine engineer, Wallis soon found his real calling in aviation industry. After a stint as a marine engineer, he switched to designing airships and engaged himself in aircraft development for Vickers. He played a crucial role in the development of the R100, the largest airship ever designed then. Following aircraft designing, Wallis concentrated his energy on bomb designing. He realized that the best way to destroy Nazi Germany’s ability to wage war is through bombing. He came up with the plan of Dambuster raid that served the purpose with less risk of causalities. For the same, Wallis invented bouncing bomb that attacked the dam walls of the Ruhr valley, disrupting German factories and their hydro-electric power. Though the bombing did not cause much of physical damage, it indeed damaged the German forces psychologically. Throughout the latter life, Wallis engaged himself in aeronautical research.
