Something wrong?He made the invisible visible. Zsigmondy's ultramicroscope let scientists see particles too small for any lens before it - work that cracked open colloid chemistry and earned him the 1925 Nobel Prize.

Richard Adolf Zsigmondy was born 1 April 1865, Austrian by birth but Hungarian by name. His research centered on colloids - those strange suspensions of particles neither dissolved nor settled - a realm where chemistry blurred into physics and nothing behaved as expected. To study what couldn't be seen, he co-invented the slit-ultramicroscope, an instrument that used scattered light to reveal particles beyond the reach of ordinary optics. The work opened a field. In 1925 the Nobel committee in Chemistry gave him the prize for it. He also developed membrane filters that became standard tools. Zsigmondy died 23 September 1929; a crater on the Moon now carries his name.
