[6] At about the time she joined the firm, Rudy produced a window for the Heinz headquarters building in Pittsburgh.
She was one of the first women admitted to the York Art Association and showed a charcoal study in the fourth annual exhibition in 1911.

Her mother was Margaret Catherine Gable Brillinger (1863-1950), Her father ran a general store in Emigsville until 1920 and then worked in local car dealerships.
[33] She had a brother, Harry E. Brillinger (1894-1918), a chemist who died in an explosion at a plant that made TNT for use in World War I.
[34] Brillinger's husband, Fritz (Frederick William Pfeiffer, 1889-1960) was, like her, an artist who made both semi-abstract and pure abstract paintings.
