20th Century
Born: Wien (Austria), 1865 
Died: Göttingen (Germany), 1929
Zsigmondy studied in Wien, München, Berlin, and Graz. He then joined a glassworks in Jena, and in 1907 he became professor in Göttingen. Zigmondy investigated glasses in the context of colloid chemistry. He recognised the resistance of hydrophilic colloids against electrolytical coagulation (protective colloids : Schutzkolloide). In 1903 together with Henry Siedentopf he developed the ultramicroscope. From 1918 he did research on ultrafiltration to determine the size of colloid particles. In 1925 he was award the Nobel Prize in chemistry.
