Vinko Dvořák (1848-1922), Czech who came from Prague to Zagreb in 1875 and was lecturing physics at the University of Zagreb, was the student of Ernst Mach. He is well known by his discoveries in acoustics, especially about acoustic forces. He was the first constructor of an acoustic radiometer, which has been unjustly attributed to Rayleigh. Information by professor Vatroslav Lopasic, professor of physics at the University of Zagreb.

Parts of acoustic radiometer constructed by Vinko Dvořák, kept in the Department of Applied Physics of the Faculty of Electrical Engineering and Computing, University of Zagreb. The aim of the instrument is to study mechanical effects of sound.
