Jules Bordet

Jules Bordet was a Nobel Prize-winning immunologist whose discoveries about complement and antibody-mediated immune destruction laid conceptual groundwork for understanding how the immune system can kill abnormal cells including cancer cells. While primarily known for microbial immunology, his work on cytolytic antibodies and complement activation provided foundational principles that underpin modern cancer immunotherapy. The Jules Bordet Institute in Brussels remains a leading European cancer center bearing his name. His intellectual legacy connects 19th century immunological biology to contemporary immuno-oncology.
