Laozi: Lao Tzu was a philosopher of ancient China, best known as the author of the Tao Te Ching (often simply referred to as Laozi). His association with the Tào Té Chīng has led him to be traditionally considered the founder of philosophical Taoism (pronounced as "Daoism"). He is also revered as a deity in most religious forms of Taoist philosophy, which often refers to Laozi as Taishang Laojun, or "One of the Three Pure Ones".
A central figure in Chinese culture, both nobility and common people claim Laozi in their lineage. He was honored as an ancestor of the Tang imperial family, and was granted the title Táishāng xuānyuán huángdì, meaning "Supreme Mysterious and Primordial Emperor". Throughout history, Laozi's work has been embraced by various anti-authoritarian movements. (Wikipedia)
