Which surgeon is associated with the first sterilised operating theatre?

• A. Gustav Neuber
• B. Louis Pasteur
• C. Robert Koch
• D. Charles Chamberland

Answer: (A)

Building a fully controlled, sterile environment for surgery was a major shift in how operations were performed. Gustav Neuber is the surgeon who first put this into practice by creating the first aseptic operating theatre in the 1880s. He designed a dedicated, clean environment with sterilized instruments, gowns, and drapes, and he controlled who entered the room to minimize contamination. This approach treated the theatre itself as a critical part of preventing infection, not just treating wounds with antiseptics.

The other names are key figures in microbiology and sterilization technology, not the surgeon who established the first sterile operating room. Pasteur helped establish germ theory; Koch identified pathogens; Chamberland developed influential filtration and sterilization tools. Their work supported the move toward asepsis, but Neuber is the one who originated the concept of a sterile theatre.
