Abstract

John Ruiz was one of the first amateur astronomers to mix photo-electric cells, vacuum tubes, and telescopes electronically. In the December, 1951, Issue of Sky & Telescope, he reported on his observations of variable stars with his 8-inch reflecting telescope and a photoelectric photometer which he had built himself. John was not only an assiduous observer, but he was also an excellent craftsman with a remarkable ability to thread his way through the complexities of electronic design. In addition, he had the capability of inspring new comers to astronomy to "go out and do likewise."
