Abstract Zhang Zigong is one of the eminent pioneers of modern chemistry and education, as well as a trailblazer in the history of science and technology in China. Dating back to the early 1940s, he and Joseph Needham have been conducting the earliest exploration in this field. Several letters from Zhang Zigong to Joseph Needham had been collected in the Needham Research Institute, which demonstrates numerous fragments of historical discussions and exchanges between the two chemists on the fields of the ancient Chinese chemistry, medicine and scientific thoughts, especially that the documents and proposals provided by Zhang has given Needham vital inspiration and assistance on conducting the works of Science and Civilisation in China. In addition, the bonding between them due to the history of science and their academic fascination reveals an admirable and touching scholarly friendship.
