William George Jordan's 1923 biography of Charles Waldo Haskins delves deep into the life and work of this esteemed and pioneering accountant, exploring what made him special and the lasting impact that he had on the world of finance.

He was famous for advocating unified and reliable counting principles, and he lectured widely on history and methodology. William George Jordan (1864 - 1928) was an American lecturer, editor, and essayist. He is most famous for his self-help books, especially those on the subject of mental training and cognitive improvement.
