Václav Jeřábek (1845–1931) was a Czech mathematician, specialized in constructive geometry.

Jeřábek studied at the lower school of Pardubice and at the higher school of Písek, then he was to Vienna and studied at Imperial and Royal Polytechnic Institute where he graduated.

Although he participated in several leading intellectual circles of Vienna, he remained a Czech with a clear view of patriotism.

[3] He published scientific articles in Czech, German and French, and longer lectures.

He is well remembered by the Jerabek hyperbola,[4] the locus of the isogonal conjugate of a point that traverses the Euler line of a triangle.
