Encyclopedia
Vinko Dvořák was a Czech
-Croatian physicist, professor and academician.
He studied mathematics and physics at the Charles University in Prague
, and after graduating he became an assistant to professor Ernst Mach
. After obtaining his doctorate in Prague in 1873/1874 he came to Zagreb
(at the time also part of Austria-Hungary
) and founded the Physics Cabinet at the Faculty of Philosophy in 1875.
Dvořák made many important discoveries in the field of experimental acoustics
and optics
, which are known as the Dvořák-Rayleigh current, the Dvořák acoustic repulsion, and the Dvořák circuit. His work on acoustic radiometer
s coincided with that of Lord Rayleigh.
He was the dean of the Faculty of Philosophy in 1881/82 and again in 1891/92 and the rector of the University of Zagreb
in 1893/94.
Professor Dvorak made constant advancements in physics experimentation at the Faculty—in 1896 he obtained a Röntgen radiation device just six months after it was discovered.
He became a member of the Academy of Sciences and Arts
in 1883 (associate) and 1887 (full member). He was also an associate member of the Czech Academy of Franz Joseph I, a member of the Société francaise de physique (French Physics Society) and the Paris Société internationale des électriciens, and a member of the Royal Czech Society of Sciences
in Prague.
Dvořák retired in 1911.
