Dialogue. From biochemistry to history of Chinese science and technology

Joseph Needham (1900-1995) is one of the greatest scholars of the 20th century with a very unique career. A biochemist he is notably with Conrad H. Waddington one of the founders of British chemical embryology. At the same time J. Needham continues to intervene in other fields of thought and science (epistemology of science philosophy politics history). Having always considered himself a scholar and a citizen socialist and Christian he became involved in political action within the English left from the 1920s. In 1937 following the arrival of young Chinese doctoral students in Cambridge he began to take an interest in the Chinese world and in particular in the sciences and techniques of this civilisation. During the Second World War he led an official mission to help Chinese scientists in the middle of the Sino-Japanese War. It was on this occasion that he matured a gigantic and unprecedented project: to make the history and analysis of all of the Chinese sciences techniques and thought. The first volume of Science and Civilisation in China written by Joseph Needham with the collaboration of Wang Ling appeared in 1954; many researchers participated in this intellectual adventure; the last volume published dates from 2015. The interview was carried out between 1988 and 1989 in a few meetings and we discover the immense knowledge originality humour mindedness of Joseph Needham.
