22 May 1957, The Evening Star (Washington, DC), “Potomac Fever” by Fletcher Knebel, pg. A-23, col. 4:

By the time I found this I had gone through a fair amount of false leads and slop, so I wanted to confirm and provide a convenient copy for future citations. The Library of Congress has helpfully digitized this page:

And here’s the page pdf for convenience.
