An English-Australian analytical chemist and early vegetarian writer, he brought a practical, science-minded voice to questions about food and health. His best-known work explores nutrition in clear, accessible terms while reflecting the reform movements of his time.

by A. W. Duncan
Born in Hull, Yorkshire, Arthur William Duncan became interested in vegetarianism as a young man after reading the work of T. L. Nichols. He later joined the Vegetarian Society in 1877 and built a career as an analytical chemist, including work in Manchester and study with the chemist Carl Remigius Fresenius.
Duncan is best remembered for The Chemistry of Food and Nutrition, a book that tried to explain diet and health through the chemistry and physiology then available to him. That combination of scientific training and reform-minded curiosity helped his writing stand out among early popular books on food.
He also emigrated to Australia, where he spent the later part of his life. While some details of his life are not widely documented online, the record that does survive presents him as a thoughtful figure at the meeting point of science, public health, and vegetarian advocacy.
