Amos Hoff

We dedicate this page to Dr. Amos Hoff, founder of the Phoenix Observatory Association and the Phoenix Astronomical Society. The following images were acquired from yearbooks archived at the Phoenix College Office of Alumni and Development. Original photo captions are provided where available.

An autographed 1963 Phoenix College yearbook provided the only color photo of our founder.

This very early photo below shows the Phoenix College astronomy class on November 12th, 1943, five years before the creation of the Phoenix Observatory Association (later to become PAS).

J.C. Astronomers Locate Venus - We have all done a little star gazing at one time or another, but the J.C. astronomy class locates planets in the middle of the afternoon. Using the school's 5-inch refractor, the students located Venus at 2:30 one afternoon several weeks ago. Mr. Hoff said in an interview, "The astronomy class has been emphasizing aerial navigation as well as astronomy, since most of the class is interested in aviation training. We are studying astronomy, meteorology, and celestial navigation." Constellation study is engaged during the day (and at night, too). Mr. Hoff said this knowledge is an important consideration in an aviator's finding his position by the stars. Astronomy is a four-hour course. There are more girls than boys in the class.

Hoff founded and moderated the Astronomy Club, pictured above right in 1947. Their main scope was Phoenix College's 5 inch Clark Refractor. It's focal length can be inferred from this nearly side-on image as approximately 2 meters. This would make it an f16 instrument.

[Astronomy Club] Availing all interested Phoenicians in general and PJC students in particular with an opportunity to view the heavens through one of the finest telescopes in the west, the Astronomy Club enjoyed one of its most active and successful years in 1946-47. The club, sponsored by Mr. Amos Hoff, owns a Clark Brothers five inch refractor type telescope. The club's purpose is to promote increased student interest in astronomy.

Amos Hoff, year unknown, relaxes with a favorite eyepiece. Note the dedication plaque on the desk behind him. It reads "Phoenix College Observatory." Note also the 24 hour clock on the wall. This is likely the interior of the roll-off observatory that for several years resided at the PC campus. The individual whose profile is shown in relief on the plaque is not unambiguously identifiable, but could be Hoff himself. The current disposition of this plaque remains a mystery.
