Her grandfather Bernt Johannessen was a prominent actor at the National Theater in Bergen in the second half of the 19th century; he was also the grandfather of the actor Per Aabel, the son of the comedian Hauk Aabel and Svanhild Johannessen, the sister of Borghild Johannessen.
Klouman was married to the actor Karl-Ludvig Bugge from 1943 to 1948, and then to Finn Rønneberg Kerr from 1950 until his death in 2001.
Klouman appeared in comic plays typical of the time such as Norman Krasna's Dear Ruth, Jens Locher's Tre må man være (It Has to Be Three),[1] and Helge Krog's På solsiden,[2] and in the film Det kunne vært deg.
She also played Eliza Doolittle in Pygmalion, operetta roles in Min søster og jeg (a translation of Georges Berr's Ma sœur et moi, My Sister and I)[3] and Die Csárdásfürstin, and a large complex character role in the psychological thriller The Gioconda Smile by Aldous Huxley, in which she delivered a sensational performance.
