Civilian Saucer Intelligence (CSI) was an independent unidentified flying object research group founded in New York City in 1954.
In contrast to the many amateurish early "flying saucer clubs", CSI actually conducted rigorous investigations of UFO reports.
Jerome Clark writes, "Though its membership was small, what the organization lacked in quantity it made up in quality of its personnel" (Clark, 188) CSI's core personnel were Ted Bloecher, Isabel Davis, and Alexander Mebane.
American biochemist Michael D. Swords describes CSI's impressive projects as the result of "the Herculean efforts of three talented UFO researchers ... [t]hey were tough analysts, very difficult to fool with trivial cases.
"[1] CSI was also notable for translating two books by French ufologist Aimé Michel into English.
