Abū Bakr Muhammad ibn Zakariyyā al-Rāzī, was a Persian polymath, physician, alchemist, philosopher, and important figure in the history of medicine.
Al-Razi took a serious interest in chemistry and in the preparation of medicines, and is sometimes referred to as the father of modern pharmacology.
He is known to have perfected methods ofdistillation and extraction, which contributed to his studies of sulfuric acid(by dry distillation of vitriol, al-zajat), andalcohol. These studies paved the way for other Islamic alchemists.
Today is his birthday anniversary.I congratulate this day to all chemists.
