In 1959, I worked as a scientist at Allied Research Associates in Boston. The company was an MIT spinoff that originally focused on the effects of nuclear weapons on aircraft structures. The company received a contract with the acronym GLIPAR (Guide Line Identification Program for Antimissile Research) from the Advanced Research Projects Agency to elicit the most creative approaches possible for a ballistic missile defense system. The government recognized that no matter how much was spent on improving and expanding current technology, it would remain inadequate. They wanted us and a few other contractors to think “out of the box.” When I first became involved in the project, I suggested that Isaac Asimov, who was a good friend of mine, would be an appropriate person to participate. He expressed his willingness and came to a few meetings. He eventually decided not to continue, because he did not want to have access to any secret classified information; it would limit his freedom of expression. Before he left, however, he wrote this essay on creativity as his single formal input.
