Melvil Dewey

• Revolutionized library organization; he was obsessed with saving time and space.
  
• Promoted the use of both shorthand and the metric system.
  
• Shortened his name from "Melville" to "Melvil"
  
• Had an anxiety about the disorder an abundance of paper documents might cause; managers at Xerox’s European research building seemed to share Dewey’s anxiety – a researcher at the building had superfluous stacks of paper on his desk, and though he was very good at navigating his way through the documents, he was asked to hide his papers when senior colleagues visited the office because of paper’s image of inefficiency
  
• Created filing cabinets, attributed to his anxiety, that were basically large versions of card catalogues; paper "hung vertically in long drawers."
