Abstract: Pascual Jordan was one of the three key founders of matrix mechanics. Due to the limitation of do- cuments, the research from Jordan＇s perspective on the Gottingen physical school was very lacking. Based on the document which was translated recently, reality has changed. The paper corrects some wrong describing and assessment on Jordan; describes and discusses the process by which Jordan became a brilliant physicist, and his important contributions to physics. The reminiscence of Jordan is a good help to resolve some problems left from the history of quantum mechanics.

Key words: Pascual Jordan, matrix mechanics, the Gottingen physical school
