Al-Razi is another name in the field of a physician in the 9th century. The full name of Al-Razi is Abu Bakr Muhammad ibn Zakariyya al-Razi who was born in 854 in Persia (Iran). He was the celebrated alchemist and Muslim philosopher. He served as a chief physician in different hospitals. Al-Razi thought of himself as the Islamic version of Socrates in philosophy and Hippocrates in medicine. Both of them were well-known personalities in Greek history.
The greatest of his work was Kitab al-Mansuri which he wrote for the Rayy ruler Mansur Ibn Ishaq and Kitab al-hawa (the comprehension book). He also wrote about Treatise on the Small Pox and Measles, which was later translated into Latin, Byzantine Greek, and various modern languages. His works were not highlighted till the 20th century and were not appreciated before. He used to claim to be a follower of Plato but his philosophies are found to be different from all the other philosophers like Al-Farabi, Ibn Sina, and Ibn Rushd.
He had also perceived atomic theory from the Greek atomist philosopher Democritus. Another major contribution is his write-up about The Spiritual Physick of Rhazes which is a popular ethical treatise and a major alchemical study. He passed away during the decade from 925-935.
