Schultz returned again to the US in December of 1945 and settled at her home on Elm Street. Through her continued American tours Schultz encouraged looking critically at both World Wars, and to remain cautious of trusting German powers. More than 500 women attended the annual Matrix banquet at the University of Wisconsin in 1949. Invited to speak, Schultz urged Americans to be less sentimental in their feelings towards Germany to ensure a lasting peace.
Schultz would never again travel to Germany after 1954 but remained vigilant, keeping current on news from Europe.
At the age of 87, Sigrid Schultz passed in her home on May 14, 1980. Due to her heroic journalism career several scholarships have been named in her honor, including one at Central Connecticut State University and Columbia University, continuing to honor her memory.
