Eduard Weyr (June 22, 1852 – July 23, 1903) was a Czech mathematician now chiefly remembered as the discoverer of a certain canonical form for square matrices over algebraically closed fields. Weyr presented this form briefly in a paper published in 1885. He followed it up with a more elaborate treatment in a paper published in 1890. This particular canonical form has been named as the Weyr canonical form in a paper by Shapiro published in The American Mathematical Monthly in 1999. Previously, this form has been variously called as modified Jordan form, reordered Jordan form, second Jordan form, and H-form.Eduard's father was a mathematician at a secondary school in Prague and his older brother Emil Weyr was also a mathematician. Eduard studied at Prague Polytechnic and Charles-Ferdinand University in Prague. He received his doctorate from Göttingen in 1873 with dissertation Über algebraische Raumcurven. After a short spell in Paris studying under Hermite and Serret, he returned to Prague where he eventually became a professor at Charles-Ferdinand University. Eduard also published research in geometry, in particular projective and differential geometry. In 1983 in Chicago, his paper Sur l'équation des lignes géodésiques was read (but not by him) at the International Mathematical Congress held in connection with the World's Columbian Exposition.
