Rueber-Staier was born in 1951 in Bruck an der Mur, Styria. She won the title of Miss Austria and participated in the Miss Universe 1969 contest, in which she was a top 15 semi-finalist. She also went on to win the Miss World 1969 pageant. During her tenure, she starred in the Bob Hope USO tour in South Vietnam.
She has lived in an Elizabethan Grade II listed house in Pinner since 1984 and moved there when she was expecting her first and only child, Ronald's son Alexander Fouracre, who lives in Willesden Green and works as a camera man. She currently lives with her second husband, publisher Brian Cowan.
She now produces metalwork sculptures; some were exhibited during Hertfordshire Visual Arts Forum's "open studios 2008".
