A. E. Van Vogt’s 1950 The Voyage of the Space Beagle is a fix-up novel of deep-space exploration.
All but one person crewing the Space Beagle are experts, knowledgeable in their own field and ignorant of any other. The one exception is the Nexialist, Dr. Elliott Grosvenor. He is a generalist who can synthesize multiple fields. Nexialism is a new field with new methods. The experts on the Space Beagle view the new field with disdain.
Pity, as only Grosvenor can prevent the utter destruction of the mission.
