Orders of Infinity: The 'Infinitärcalcül' of Paul Du Bois-Reymond

G. H. (Godfrey Harold) Hardy

1877–1947

A brilliant English mathematician who championed pure mathematics, he is remembered both for landmark work in number theory and analysis and for recognizing Srinivasa Ramanujan’s extraordinary talent. His writing, especially A Mathematician’s Apology, also made him one of the most memorable literary voices in mathematics.
