His general ideas about the elemental structures of living organisms, though specifically incorrect, anticipated the subsequent identification of the cell and development of cell theory. He was also a founder of scientific congresses or meetings.

His prescient theory described all organisms as composed of so-called infusoria (i.e., single cells) that divide.
