# Eduard Weyr

### Born: 22 June 1852 in Prague, Bohemia (now Czech Republic)

Died: 23 July 1903 in Zábori, Bohemia (now Czech Republic)

**Eduard Weyr**'s father Frantisek Weyr was born in Náchod in 1820. Frantisek was a professor of mathematics at a realschule (secondary school) in Prague from 1855. Eduard was four years younger than his brother Emil Weyr who also became a famous mathematician. Eduard attended the realschule in Prague where his father taught, then studied at the Prague Polytechnic and the Charles-Ferdinand University of Prague. By the age of sixteen he had already sent two papers to the Academy in Wienna. After studying in Prague, he went to Göttingen where he obtained his doctorate in 1873. He then went to Paris where he studied under Hermite and Serret. He returned to Prague where he was appointed as an assistant in descriptive geometry. After being appointed as a Privatdozent at the Polytechnic in Prague in 1875 he was appointed as a Privatdozent at the Charles-Ferdinand University of Prague in 1876. He became a professor there in 1881. In 1885-6 he took lectures of Kronecker and Weierstrass in Berlin. In 1902 professor at Charles-Ferdinand University of Prague but died soon after being appointed.

Eduard Weyr wrote geometrical papers and books mainly in projective geometry and differential geometry. He also worked on algebra, in particular studying linear algebra, matrices and hypercomplex systems.

Weyr published *Differential calculus* in 1902. This led to controversy with a young mathematician J V Pexider who sharply criticised Weyr's textbook. Jindrich Beèváo and Ludek Zajièek give an interesting account of this episode in a paper in the book [1].
