Charles_Méray

Hugues Charles Robert Méray (12 November 1835, in Chalon-sur-Saône, Saône-et-Loire – 2 February 1911, in Dijon) was a French mathematician. He is noted as the first to publish an arithmetical theory of irrational numbers. His work did not have much of a role in the history of mathematics because France, at that time, was less interested in such matters than Germany.He was an Invited Speaker of the ICM in 1900 in Paris; his contributed paper was presented by Charles-Ange Laisant.
