In 1948, Spitzmüller was appointed to the highest level of Curator in the governmental rankings, and remained at the Albertina until 1954.
During this time, she worked on some of the first "little guides" to the Albertina’s collections, part of her ongoing efforts to make the collections more accessible.
In 1953, she traveled to the United States to study graphic collections there; she once again saw Cott, and became lifelong friends with Agnes Mongan, curator of drawings at Harvard's Fogg Art Museum.
Returning to Vienna, she left the Albertina to move to the Kunsthistorisches Museum, where she worked to make the museum more accessible to the public, to encourage school visits, and to sponsor symposiums and lecture series; she also was a founding member of the Austrian chapter of Zonta International.
When she reached mandatory retirement age in 1969, she was given the title of Hofrat and made an honorary member of the Österreichischen Kunsthistorikerband; she also received the Chevalier ribbon of France's Ordre des Arts et des Lettres.
In that same year, she gave a talk at the Library of Congress in Washington, D.C., on Bruegel's paintings.

In retirement, Spitzmüller continued teaching groups of American students through the Austro-American Institute of Education, which she had done since the 1930s (except during the war).
In particular, she established a relationship with Hope College in Michigan, which brought groups of students to Vienna for summer school.
In 1987, Hope College honored her in conjunction with an exhibition of Viennese art at the school.

Spitzmüller was also a talented musician, and participated in many activities involving the Vienna Philharmonic.
In 1993, the Albertina, as part of a video history of the institution, interviewed her with special focus on her time there.
She died September 25, 2001, at the Heim der Kaufmannschaft in Vienna.
