1863-1942

British mathematician whose research included studies in orthogonal series (including Fourier). All books on advanced calculus now in use retain his approach to functions of many complex variables. Young was president of the London Mathematical Society from 1922 to 1924, after having earned the society's De Morgan Medal in 1917. He was also a Fellow of the Royal Society and was awarded its coveted Sylvester Medal in 1928. During World War II, Young was working in Switzerland when France fell to the Nazis. He died there in 1942, separated from his wife (the famous mathematician Grace Chisholm) and his family.
