Lao Tzu ( - c. 550 BCE)

Lao Tzu (6th century BCE) 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".
