[9] When World War II started, he enlisted and served four years as a control tower operator[12] and rose to the rank of a staff sergeant (SSgt) in the Army Air Forces.[9][14] After the war, he returned to Fresno and married Armenouhi "Armen" Kulhanjian, and they tried for a time to be grape growers.[9] Bagdasarian's Broadway debut was in 1939 when he played the newsboy in The Time of Your Life by William Saroyan, his cousin.[16] It is an adaptation of an Armenian folk song Bagdasarian wrote with his cousin William Saroyan.The executives at Liberty Records suggested that he adopt a pseudonym as they thought his name too difficult to pronounce.[9] In December 1956, he charted with his first record credited to his David Seville pseudonym, and "Armen's Theme" reached No.[29] Bagdasarian's rise to prominence came with the song "Witch Doctor" in 1958,[30] which was created after he experimented with the speed control on a tape recorder bought with $200 (equivalent to $2,100 in 2023) from the family savings.[37] Shana Alexander, writing for Life magazine in 1959, noted that Bagdasarian was the first case in the "annals of popular music that one man has served as writer, composer, publisher, conductor and multiple vocalist of a hit record, thereby directing all possible revenues from the song back into his pocket."[17] Bagdasarian died of a heart attack at his home in Beverly Hills on January 16, 1972, eleven days before his 53rd birthday.[31] He resumed the franchise with his wife Janice Karman in the late 1970s, after finishing law school,[20] and became the complete owner when he bought the rights from his siblings in the mid-1990s.
