SZERELMEY, Miklós (1803—1875). Engineer.

The inventor of the still world-widely used stone-conserving liquid: the Szerel- mey stone liquid. Szerelmey did not confine himself to 9tone preservation but branched out into several other fields, one of the more important of which was his „Zopissa Board”, the forerunner of the modern bonded-resin products.

THAN, Károly (1834—1908). Chemist.

He was the first to discover carbonoxysulphide in the gases of the Harkány spas and later synthetized it in the laboratory. He introduced potassium bicarbonate as titrimetric standard, and his methods for the analysis of gases were precise. He defined molecular volume in chemistry, and proved the atomic structure of electricity. His definition of ohemical affinity was verbatim adopted as a model.

VÁSÁRHELYI, Pál (1795—1846). Hydraulic engineer.

Vásárhelyit achievements include the regulation of the Tisza river, the construction of the Irongate and the Széchenyi road along the Danube and from 1829 on, the direction of the Danube survey project. His most significant theoretical work was a study on verifying the parabolic distribution of velocities in the vertical direction, an investigation of a pioneering character.
