Richard Saul Wurman

Richard Saul Wurman (born March 26, 1935) is an American architect, author, information and graphic designer. Wurman has written, designed, and published over 90 books and created the TED conferences and TEDMED, conferences on health and medicine. Wurman received the Lifetime Achievement award from Cooper Hewitt and the AIGA Gold Medal for his work in information design.

In his book Information Anxiety (1989), Wurman developed the LATCH principles, or "Five Hat Racks", offering a framework for organizing information. LATCH, an acronym, stands for Location, Alphabet, Time, Category, and Hierarchy. These principles provide a finite set of ways to structure information, regardless of the subject matter, making it easier to understand and navigate.
