A pretty, diminutive (4'11") actress of the silent and early sound era, Barbara Cloutman (later Kent) was born in Gadsby, Alberta, Canada on December 16, 1907. Upon graduating from Hollywood High School in 1925, Kent won the Miss Hollywood Pageant, and set her sights on a career in the movies. She was 18 when Universal Studios signed her; she made her film debut in the western Prowlers of the Night (1926). That same year, Kent established herself with the classic romantic melodrama Flesh and the Devil (1926), in which she played the rival to femme fatale Greta Garbo's affections for John Gilbert. She was loaned to MGM for that movie. Kent was selected as one of the WAMPAS Baby Stars of 1927 as a result of the popularity of her film No Man's Law (1927), in which she had a nude scene.

Kent subsequently appeared opposite Richard Barthelmess in The Drop Kick (1927) and had a starring role in another silent classic, Hicran (1928), before smoothly making the transition to talkies. She played Harold Lloyd's love interest in his first two sound movies, Evel Allah (1929) and Kunduracı (1930). Kent had supporting parts opposite Gloria Swanson in Indiscreet (1931) and Marie Dressler in Emma (1932), as well as playing the role of the aunt in Oliver Twist (1933) (notable since the character is often omitted from dramatizations of the novel).

In 1933, Kent took a year-long hiatus from acting so that her new husband, talent agent Harry E. Edington, could groom her for what he intended to be a high-profile return. Unfortunately, Kent's popularity had declined by the time she did return. She made three more films between 1935 and 1941, before retiring from the screen.

Edington died in 1949, and Kent remarried in 1954, to Jack Monroe, an engineer. They settled in Palm Desert, California, where Kent remained after Monroe's death. Her retirement was long and peaceful; she passed away on October 13, 2011 at the age of 103.
