Abu Nasr Muhammad al-Farabi, also known as Alpharabius in the West, was a prominent Islamic philosopher, scientist, and music theorist who lived from around 870 to 950 AD. He made significant contributions to various fields including philosophy, logic, political science, metaphysics, and music, earning him the title "The Second Teacher" after Aristotle. Al-Farabi's works, which combined Greek philosophical concepts with Islamic thought, greatly influenced subsequent Muslim scholars and played a crucial role in preserving and transmitting ancient Greek knowledge to the Islamic world.
