BOOK REVIEW: The Visioneers: How a Group of Elite Scientists Pursued Space Colonies, Nanotechnologies, and a Limitless Future by W. Patrick McCray

Review by Sid Perkins

In the wake of the Manhattan Project and the Apollo program, almost anything seemed possible. And some scientists of the late 20th century went beyond the fanciful notions of futurists and science fiction writers to seriously explore where technology might take humans, society and culture.

McCray chronicles the main players in two trends that captured imaginations at the time, focusing on notable techno-evangelists Gerard O’Neill, a Princeton physicist who advocated colonizing space, and MIT-trained engineer Eric Drexler, who championed nanotechnology.
