After WWII her family was placed in an American controlled resettlement camp where they received permission to emigrate to the United States and eventually settled in San Francisco. When the 1959 film Gidget became a hit, a local San Francisco television station held a beauty and talent contest to crown a teenage girl as "Miss Gidget" on the "Dick Stewart Television Show." Barbara won and was also offered the chance to be one of the regular dancers on the rock 'n' roll show "The KPIX Dance Party." She was on the show from 1959 until 1962. She then moved to Hollywood to make a name for herself, but not with her Germanic last name. She changed that to the French sounding Bouchet.
From The Grindhouse Cinema Database:
For classic exploitation film fans she is widely known as a stunning beauty who has had memorable parts in Italian genre films like the gialli The Black Belly of the Tarantula (1971), The Red Queen Kills 7 Times, Don't Torture a Duckling (1972) and poliziotteschi (Italian crime-action films) such as Caliber 9 (1972), Ricco the Mean Machine (1973) and Death Rage (1976)."
With the release of many of her films on DVD and Blu-ray, her status as a cult film legend continues to grow. She still lives in Rome with her family and continues to work in the film and television industry.
