James Mactear

Born in Glasgow on April 3, 1845, James Mactear built his career in industrial chemistry and chemical engineering. He worked in manufacturing chemistry from a young age, later managing major chemical works in Scotland and developing new processes and equipment used in alkali production and related industries.

After retiring from factory management, he moved to London and worked as a consulting chemical expert and engineer, with a special focus on mining and metallurgy, especially quicksilver and gold extraction. He also wrote papers on chemical subjects, earned recognition from scientific institutions, and became known in his time for both practical invention and research.

On the Antiquity of the Chemical Art reflects that blend of hands-on science and historical curiosity. In it, he argues that the roots of chemistry stretch far back into ancient Indian, Persian, Egyptian, Greek, and Arabian traditions, showing his interest not just in how chemistry worked, but in how it came to be understood across cultures.
