Razi was a versatile
Persian physician, philosopher, and scholar who made fundamental and enduring contributions to the fields of
medicine,
alchemy, and
philosophy, recorded in over 184 books and articles in various fields of science. He was well versed in
Greek medical knowledge and added substantially to it from his own observations. As an alchemist, Razi is credited with the discovery of
sulfuric acid, the "work horse" of modern
chemistry and
chemical engineering. He also discovered
ethanol and its refinement and use in
medicine. He was unquestionably one of the greatest thinkers of the
Islamic World, and had an enormous influence on European science and medicine.
Razi was a pure
rationalist, extremely confident of the power of reason; he was widely regarded by his contemporaries and biographers as liberal and free from any kind of prejudice, very bold and daring in expressing his ideas without a qualm. He believed in man, progress and in "God the Wise".
