Her family was living in poverty until 1948 when they sought asylum in Vienna and Salzburg as the communist regime began to take hold in Hungary. In 1950, her family emigrated to the States and Baron von Schell Bauschlott renounced his title in order for his family to gain citizenship. Catherine entered a convent school in New York's Staten Island area. 

In 1957, her father joined Radio Free Europe, taking the family to Munich where she developed an interest for acting and trained at the prestigious Falconberg School.

Her career began to wane by the time she did the film Wish Me Luck (1995) in 1990 and she retired shortly thereafter, running a small guest hotel in France.
