Omarr was born Sidney Kimmelman in
Philadelphia to a middle class
Jewish family. His father worked as a grocer. In elementary school, he had a strong interest in magic performances, and he performed at talent shows and magic shops. Omarr decided to change his name when, at age 15, he saw a movie called
Shanghai Gesture starring
Victor Mature as a character named Omar, with one "r." He had a strong interest in
numerology, which led him to change Sidney to Sydney, and add an extra "r" to Omarr. During
World War II, Omarr, 17, joined the
United States Army; he claimed he chose April 4, 1944 as the day to sign due to the numerological benefit of a date composed of "all fours." Approximately a year later he was transferred to the
Air Force at a base located in Ontario, California, approximately 35 miles east of Los Angeles and referred to as 'Camp Hollywood.' Omarr said that he was posted to
Okinawa, Japan within a year of joining the army, and was able to specialize in astrology with his weekly Armed Forces Radio Program ''Sydney Omarr's Almanac
, broadcast throughout the Pacific Theatre. He attempted to predict the results of various sporting contests and events. After gaining transfer to Camp Ontario in April 1945, Omarr was profiled by Wings'', the Air Force's official counterpart to
Stars and Stripes. In this semi-satirical profile, Omarr is quoted as predicting the
Japanese defeat in "mid-August, 1945." Although the author of this piece subsequently stated that this quote was apocryphal and was part of the general satire, Omarr subsequently used it to promote his astrology career, ultimately gaining an influential column at the
Los Angeles Times. Omarr also claimed he wrote the
horoscope column for the U.S. Army's
Stars and Stripes newspaper. ==Career as writer and media astrologer==
