Alchemist: Someone Who Transforms Things for the Better
Alchemy and alchemist are in fact older words than chemistry and chemist in English. Alchemists believed that lead could be “perfected” into gold, that diseases could be cured, and that life could be prolonged through transmutation, or a change of some essential element into a superior form.
Their secretive experiments, usually involving heat and the mixing of liquids, led to the development of pharmacology and the rise of modern chemistry.
Alchemy is the power to change or create things in a way which seems mysterious and magical. This power to transform things for the better, real or imagined, led to figurative meanings for alchemy and alchemist.
