Jabir ibn Hayyan, often referred to as the 'father of chemistry,' was a Persian alchemist and polymath who lived during the 8th century. He is renowned for his extensive contributions to alchemy and early chemistry, which laid the groundwork for modern scientific methods and practices. His work not only focused on the transformation of substances but also emphasized the importance of experimentation and observation, bridging the gap between mystical alchemical traditions and systematic scientific inquiry.
