At first Hadamard, like many people, assumed that Dreyfus was guilty.

However after moving to Paris in he began to discover how evidence against Dreyfus had been forged. He became a leading member of those trying to correct the injustice. The case split France into two opposing camps leading to issues far beyond the guilt or innocence of Dreyfus. There were demands to bring Zola to justice, anti-Semitic riots broke out, and there was a petition demanding that Dreyfus be retried.

Zola was sentenced to a year in prison and fined 3francs. By there had been a confession to the forgeries, followed by a suicide, and Dreyfus was retried, again found guilty, but pardoned. Hadamard took an active part in clearing Dreyfus's name which finally happened on 22 Julywhen Dreyfus was reinstated and decorated with the Legion of Honour.

Laurent Schwartz wrote see for example [ 27 ] :- It is the Dreyfus Affair which was in the sense of defence of justice the great affair of [ Hadamard's ] life. From the moment when he understood the enormity of the injustice perpetrated against a man in the name of reason of state, and the consequences which anti-Semitism could have, he devoted himself passionately to the review of the trial.

This affair marked his life. Long before the Dreyfus Affair had ended Hadamard had, as we have indicated, moved from Bordeaux to Paris. This volume on two dimensional geometry appeared inand was followed by a second volume on three dimensional geometry in This work had been requested by Darboux and it went on to have a major influence on the teaching of mathematics in France.

Hadamard received the Prix Poncelet in for his research achievements over the preceding ten years. His research turned more towards mathematical physics from the time he took up the posts in Paris, yet he always argued strongly that he was a mathematician, not a physicist. He believed that it was the rigour of his work which made it mathematics.

In particular he worked on the partial differential equations of mathematical physics producing results of outstanding importance. His famous work on geodesics on surfaces of negative curvature laid the foundations of symbolic dynamics. Among the topics he considered were elasticity, geometrical optics, hydrodynamics and boundary value problems.

He introduced the concept of a well-posed initial value and boundary value problem. He continued to receive prizes for his research and he was further honoured in with election as President of the French Mathematical Society. He wrote later that his many years of "pure joy", beginning from the time of his marriage, came to an end in It was World War I which led to a great tragedy for Hadamard with his two older sons being killed in action.

On creativity. In his book Psychology of Invention in the Mathematical Field, Hadamard uses introspection to describe mathematical thought processes. In sharp contrast to authors who identify language and cognition, he describes his own mathematical thinking as largely wordless, often accompanied by mental images that represent the entire solution to a problem.

He surveyed of the leading physicists of the day approximatelyasking them how they did their work. Hadamard described the process as having four steps of the five-step Graham Wallas creative process model, with the first three also having been put forth by Helmholtz:[8] Preparation, Incubation, Illumination, and Verification.
