Abstract: As a great master of physics Max Born had affected and trained a large number of physicists and other scientists directly in the 20 th century. Yukawa Hideki was not the pupil of Max Born,but he was affected greatly by the academic thought of Max Born when he entered university,and he never forgot it. Yukawa Hideki treated Born as his model to learn from. They had the same thought not only on scientific problems,but also on many scientific- social issues. Max Born earned the respect of the young scientists who were not his pupil by his books.Yukawa Hideki found that Born was a predecessor who had the same personality with him. He imitated the Born＇s style when he studied and learned something,and obtained his success. The both sides of the story were worthy of attention by the predecessor and the young generation in China.

Key words: Max Born, Yukawa Hideki, reciprocity theorem
