About Dilbert.

Dilbert is the eponymous main character of the Dilbert comic strip. He has a rare condition characterized by an extreme intuition about all things mechanical and electrical (and utter social ineptitude), an idea that was explored in the animated television episode titled "The Knack". He graduated from the Massachusetts Institute of Technology with a degree in Electrical Engineering. Although his ideas are typically sensible and occasionally even revolutionary, they are seldom carried out because of his powerlessness. He is easily frustrated by the incompetence of his co-workers (most often the Pointy-Haired Boss) and is often sarcastic and snide. Dilbert's unusual name was suggested to Scott Adams by a co-worker; Adams later found that the name likely came from a cartoon character used by the United States Navy during World War II.

In an interview with The New York Times Adams said that he based Dilbert's character on someone he knew, saying: "I worked around engineers for most of my 16 years of corporate life. Dilbert is actually designed after one person in particular. Interestingly, that person is not aware that he is the model for Dilbert. I didn’t know him well and never mentioned it to him.
