1825–1874
A pioneering 19th-century German microscopist, he helped reshape how scientists understood cells and tissues. His work on the structure of protoplasm and on blood cells made him an important figure in early cell biology.

by Max Schultze
Born on March 25, 1825, Max Schultze was a German anatomist, histologist, and microscopist whose research helped push microscopy into a new era. He worked at a time when scientists were still debating the basic nature of cells, and he became known for careful observation and clear scientific argument.
Schultze is especially remembered for his studies of cell structure and for promoting the idea that the essential living substance of both plant and animal cells was protoplasm. He also carried out influential work on connective tissue, muscle, sensory organs, and blood, including studies that helped clarify the nature of platelets and other microscopic components of the body.
He spent much of his career in Bonn, where he taught and conducted research, and he also founded an important journal devoted to microscopic anatomy. Although he died relatively young, on January 16, 1874, his work had a lasting effect on histology and cell biology, and his name remains closely tied to the development of modern microscopic science.
