Index. How did Pierre Fatou and Gaston Julia create what we now call Complex Dynamics in the context of the early twentieth century and especially of the First World War The book is based partly on new unpublished sources.Who were Pierre Fatou Gaston Julia Paul Montel New biographical information is given on the little known mathematician that was Pierre Fatou. How did the serious WW1 injury of Julia influence mathematical life in France From the reviews of the French edition: Audin’s book is indeed filled with marvelous biographical information and analysis dealing not just with the men mentioned in the book’s title but a large number of other players too … . the book under review addresses itself to scholars for whom the history of mathematics has a particular resonance and especially to mathematicians active or even with merely an interest in complex dynamics. … presents it all to the reader in a very appealing form.
