Heinrich Wilhelm Waldeyer

Heinrich Wilhelm Waldeyer was a German anatomist and histologist known for his significant contributions to cell theory and neuroanatomy. He described important structures in the nervous system, such as the "Nissl bodies" and the "Waldeyer’s ring," a ring of lymphoid tissue in the throat that helps defend against infection. His work helped scientists better understand how the nervous system and immune system function. Waldeyer’s research advanced medical knowledge of anatomy and cell biology, influencing both research and clinical approaches to understanding human health.
