Paul Ehrlich (1854–1915) was a groundbreaking German physician and scientist who made significant contributions to immunology, chemotherapy, and hematology. He is best known for his theory of the immune system, which led to the development of the side-chain theory, explaining how antibodies are formed in response to infections. Ehrlich’s work in staining techniques also revolutionized…
Paracelsus (1493/1494–1541) was a Swiss-German physician, alchemist, and philosopher who revolutionized medicine and pharmacology during the Renaissance. Born Theophrastus von Hohenheim, he adopted the moniker “Paracelsus” to signify his departure from traditional medical practices. Rejecting the prevailing Galenic system, Paracelsus emphasized observation, experimentation, and the use of chemicals in medicine, laying the groundwork for modern…
