Grace Voss Frederick (November 3, 1905 – January 16, 2009) was an American actress on the Broadway stage and on television when it was still an experimental medium.

The museum, located in Cave Creek, Arizona, contains art, antiques, and other items of historical interest mainly from the 19th and 20th centuries.

To preserve the natural environment and her museum collection, in 2001 she donated 90 acres (360,000 m2) of her land and US$6 million to the Arizona State University Foundation.

[8][11] She was a leading lady at the Children's Theater section of the Princess Theatre in Manhattan, which was operated by Clare Tree Major, starring in productions of well-known fairy queens and the 1926 run of "Cinderella".

[15] Ann Hood was the starring role in the play, and Voss received praise for her portrayal of a young flapper intent upon having adventures before she marries.

[12] In addition to acting on the stage, Voss gave orations around New York state at various recitals, civic functions, and women's club meetings from the early 1920s through the first half of the 1930s.

[21] She appeared as the principal pantomimist in nineteen episodes of dramatic programming created for the Columbia Broadcasting System on W2XAB in 1931, and also in 1932 for the bicentennial of the birth of George Washington.

[7] Within two years, she expanded the business to include beauty services, like hair and make-up, so that her clients could be sure that their best features would be brought forward and their unflattering traits would be minimized.

[28] They formed Jenfred, Inc., a firm based in New York City that specialized in creating background images for live television productions.

[31][32] The machine, which they called the "Threeplex", used three lenses to manipulate images and create composites so that they could effect change or rotation making more realistic imagery.

[8][28] They eventually settled in Cave Creek, Arizona, when the Sierra Vista Dude Ranch was broken up into individual parcels in 1971.

[8][28] Frederick also served as president of the Cave Creek Community Association, an organization formed for area business development.

[8][34] In 1980, the couple converted their garage into a small museum focused on home entertainment, including radios, televisions, magic lanterns, phonographs, and even a player piano.

[11] She also developed a theater for community plays to be performed, which was adjacent to the museum with plans to expand it to be able to accommodate 100 people and feature a rooftop observatory for astronomical observation.
