Which pairing correctly identifies the person and anaesthetic for a major breakthrough?

• A. Humphrey Davy - nitrous oxide
• B. James Simpson - chloroform
• C. Robert Liston - ether
• D. William Morton - antiseptic technique

Answer: (B)

The main idea here is identifying who established a major turning point in pain-free surgery by linking a specific substance to effective anesthesia. James Simpson, a Scottish physician, tested several inhaled substances and identified chloroform as a powerful, controllable anaesthetic in the late 1840s. Its adoption brought reliable unconsciousness for a wide range of operations and even childbirth, transforming how surgeons could work and how patients experienced procedures. This made anesthesia a standard part of medicine, not just a curiosity, which is why the pairing with chloroform stands out as the best example of a major breakthrough.

Humphrey Davy’s nitrous oxide work was important earlier as a scientific curiosity, but it didn’t become the practical standard for major surgery. Robert Liston is associated with early ether use, yet the most celebrated, widely recognized breakthrough for Britain’s medical practice is Simpson’s chloroform. William Morton’s ether demonstration is indeed landmark, but antiseptic technique matters separate from anesthesia, so that pairing mixes two different breakthroughs.
