French mathematician (1865-1963) who made major contributions in number theory, complex function theory, differential geometry, and partial differential equations. TLS in French, signed “J. Hadamard,” one page, 5.25 x 8.25, October 19, 1933. Letter to a gentleman, in part (translated): "The surrogate geometry of bee cells has been known for a long time. I do not know if any further remarks have been made on this subject, and it will be necessary to make sure of a little study of it that I can not think of taking it. You will certainly find other mathematicians that this question may be of interest." In fine condition, with a crease, and small chip, toe the left edge.
