1903 - Karl Ducker Was Born
Ducker was a Gestalt psychologist. He is known for introducing the concept of functional fixedness, an obstacle in problem-solving in which people tend to view problems only in their customary manner. Functional fixedness prevents people from fully seeing all of the different options that might be available to find a solution. Ducker emigrated to the U.S. and worked as an assistant for Wolfgang Kohler before committing suicide at the age of 37.
