Obed Simon Johnson
Obed Simon Johnson (May 5, 1881 – October 12, 1970) was an American academic, chaplain, congregational missionary and student of Chinese culture and history, known for A Study of Chinese Alchemy, which attributes the origin of alchemy to ancient China, rather than Greco-Egyptians 500 years later. He was the first Westerner to recognize the ancient Chinese alchemists.
