Chemistry: 1925

Zsigmondy, Richard pronounced ZHIG mawn dee, (1865-1929), an Austrian chemist, studied the manufacture of colored glass which contained finely divided gold particles. From this research, he developed the ultra-microscope and other pieces of apparatus which aided the study of colloid chemistry. He won the 1925 Nobel Prize for chemistry.

Zsigmondy was born in Vienna, Austria. He studied and taught at Berlin, Germany, and the University of Graz in Austria. From 1897 to 1903, he carried on research on colloids in glass at Jena, Germany. He served as director of the Institute for Inorganic Chemistry at the University of Gottingen from 1907 until his death.
