Richard Adolf Zsigmondy (1865–1929) was an Austrian chemist who won the Nobel Prize in Chemistry in 1925 for his work in developing the ultramicroscope, an instrument that allowed for the observation of colloidal solutions and small particles that were previously difficult to study. His contributions were significant in the field of colloid chemistry and helped advance our understanding of particle size and distribution in various materials.
