Who is Mr. Partridge from Reminiscences of a Stock Operator and what is their importance?

Mr. Partridge is an older trader at Fullerton's whom Livingston seems to admire. Mr. Partridge listens attentively and kindly to the younger traders who are eager to tell him their tips or get his approval of their latest trade. He seldom says anything or gives advice, except in the most general way. Livingston eventually figures out that Mr. Partridge is trying to make a point about trading with the general trend of the market, rather than paying so much attention to the ups and downs of individual stocks.
