Muhammad ibn Zakariyā Rāzī , known as Rhazes or Rasis after medieval Latinists, (August 26, 865, Rey -- 925, Rey) was a Persian physician, alchemist and chemist, philosopher, and scholar . He is recognised as a polymath. Numerous "firsts" in medical research, clinical care, and chemistry are attributed to him, including being the first to differentiate smallpox from measles, and the discovery of numerous compounds and chemicals including ALCOHOL and kerosene, among others. Edward Granville Browne considers him as "probably the greatest and most original of all the physicians, and one of the most prolific as an author"
