With her innate talent and drive, it was not too difficult to decode actress Barbara Feldon's formula for success. The former fashion model shot to fame as the statuesque Agent 99 on the classic spy sitcom "Get Smart" (NBC, 1965-69; CBS, 1969-1970), which paired her with Don Adams as the blundering, shrill-voiced Maxwell Smart. Playing the highly competent secret agent whose looks often came in very handy during covert operations punctuated Feldon's career, but it also limited her choice in roles following the show's demise. Feldon continued to act, taking on supporting roles on various drama series and sitcoms, as well as earning recognition as a brilliant voiceover artist. Yet, it was Feldon's role as the slick and sexy Agent 99 that was forever etched in most viewers' memories, making her one of television's most unforgettable characters.
