Reuben Lucius Goldberg graduated with an engineering degree from the University of California. After 6 months of working at a water and sewers department, he changed his career and became a cartoonist. His cartoons were pictures of complicated inventions that did simple tasks. For example, he might have a 12-step process to use a napkin at the table. He also used odd materials such as pets, food items, clocks, and gears in his inventions.
