Max Schultze
1825–1874
Remembered for changing how scientists understood the cell, this 19th-century German anatomist helped shift attention to protoplasm as the living substance shared by plants and animals. His microscope work also advanced the study of tissues, blood cells, and the retina.

About the author
Born in Freiburg im Breisgau on March 25, 1825, Max Johann Sigismund Schultze was a German anatomist and zoologist whose career was shaped by medicine, microscopy, and careful laboratory observation. He studied at Greifswald and Berlin, taught at Halle, and later became professor of anatomy and histology and director of the Anatomical Institute at Bonn.
Schultze is best known for his work on cell theory. In the early 1860s, he described the cell in a way that emphasized protoplasm with a nucleus, helping move biology away from older ideas that treated the cell wall as the defining feature. He also made important contributions to histology and microscopy, including studies of blood cells, protozoa, and the retina.
Although he died relatively young in Bonn on January 16, 1874, his influence lasted well beyond his lifetime. His research helped make the microscope a central tool of modern biology, and his ideas became part of the foundation for later work in cell biology and physiology.
