Mathematical Treasure: Textbooks of Sylvestre Lacroix

Sylvestre Lacroix (1765-1843) was a French mathematician and Professor of Mathematics in several post-revolutionary French institutions of higher education. He spent much of his career teaching at the École Polytechnique in Paris. Lacroix was a textbook writer of wide scope who incorporated into his works the revolutionary concept that knowledge should be for public consumption. As a result of this innovation, his textbooks were adopted, sometimes after translation, throughout Europe and the early United States of America.
