A childhood photograh of Sir Barnes Neville Wallis (1887-1979) the British aeronautical engineer, who became famous for inventing the bouncing bomb. Wallis designed the R100 airship for Vickers Armstrong but, when the R101 crashed, Wallis began producing aircraft designs which combined lightnes with strength and applied these principles to the 'Wellesley' and 'Wellington' bombers. After the succes of his bouncing bomb, Wallis was allowed by the authorities to produce heavy, penetration bombs such as the 'Tallboy' and 'Grand Slam'.
