I found it in the Wikipedia article about John E. Arnold who taught creativity in engineering at MIT in the 1950s. He was a member of the MIT Science Fiction Society.

Arnold's philosophy of creativity and design emphasized the individual because "Every new combination of values ... is formed in the mind of an individual man." ... Accordingly, he advocated personal development first and foremost, providing guidelines for self-reflection and idea generation, a form of metacognition.

According to Arnold, some people believed that individuals could not invent because society and the sciences had become too complex—"no man can know all and therefore no man can invent." Consequently, these people overemphasize teamwork. Arnold said such efforts will fail because "the creative process is an individual process and, as John Steinbeck said, 'it lies in the lonely mind of a man.'"
