Which chemist Cadet de Vaux campaigned for hygiene improvements in public infrastructure and food manufacturing, published 'Instruction on the Art of Making Wine' in 1800, and invented the gleuco-oenometer to measure residual sugar?

• A. Louis Pasteur
• B. Jean-Antoine Chaptal
• C. Antoine-Alexis Cadet de Vaux
• D. Nicolas-Theodore de Saussure

Answer: (C)

This question tests recognition of a chemist who bridged public health reform with practical wine science in the early 1800s. Antoine-Alexis Cadet de Vaux is the figure who fits all three clues. He actively campaigned for hygiene improvements in public infrastructure and in food manufacturing, reflecting the era’s push toward sanitation in industry. He published Instruction on the Art of Making Wine in 1800, providing structured guidance for winemaking and quality control. He also invented the gleuco-oenometer, a device to measure residual sugar in must and wine to gauge fermentation progress and sweetness, enabling more precise control over the final product. This combination of public-health advocacy, an influential wine-making manual from that period, and an invention for sugar measurement points to Cadet de Vaux rather than the other chemists listed.
