چکیده
Joseph Needham [4] was an embryologist and biochemist who is most noted in science for his studies on induction [5] in developing embryos. Needham worked with Conrad Hal Waddington [6] to attempt to identify the compound responsible for the organizer?s activity. Although he was not successful in discovering the chemical, he and Waddington learned much about the organizer [7]. Needham was a meticulous writer, writing reviews and books about contemporary research. In later years, Needham traveled to a newly opened China and studied their history, writing a number of books on Chinese culture, science, and history. Born Noel Joseph Terrence Montgomery Needham on 9 December 1900 in London, his parents were Alicia Adelade Montgomery and Joseph Needham [4]. His parents? relationship ended poorly while he was a child and he was often forced to mediate between them, a skill he utilized in later years. He pursued science and philosophy, subjects that also interested his father.
