Next year she set four world records in the 400 m and 500 m breastroke, but could not compete in the Olympics due to the overall financial problems related to the Great Depression. She won the national titles in the 200 m in 1933, 1935 and 1936, yet her performance declined, and at the 1936 Summer Olympics she finished in a mere seventh place.
