Isaac Asimov is one of the most prolific writers of the 20th century, dying at the age of 72 in 1992.

He is best known for his Robot series, wherein he created the Three Laws of Robotics in his short story "Runaround" (1942). The First Law is that a robot may not harm or allow to come to harm any human being. The Second Law is that a robot must obey orders given to it by human beings as long as it doesn't conflict with the First Law, and the Third Law is that a robot must not allow itself to come to harm as long as it doesn't conflict with the First and Second Laws.
