She was the First Lady of the United States from 1923 to 1929 and the Second Lady of the United States from 1921 to 1923. She graduated from the University of Vermont in 1902 with a bachelor of arts degree in teaching and joined the Clarke Schools for Hearing and Speech in Northampton, Massachusetts, to teach deaf children to communicate by lip reading, rather than by signing.

Document 2: Universal Pictures: The production arm of the studio still struggled. While there were to be a few hits like The Killers (1946) and The Naked City (1948), Universal-International's new theatrical films often met with disappointing response at the box office. By the late 1940s, Goetz was out, and the studio returned to low-budget films. The inexpensive Francis (1950), the first film of a series about a talking mule and Ma and Pa Kettle (1949), part of a series, became mainstays of the company. Once again, the films of Abbott and Costello, including Abbott and Costello Meet Frankenstein (1948), were among the studio's top-grossing productions. But at this point Rank lost interest and sold his shares to the investor Milton Rackmil, whose Decca Records would take full control of Universal in 1952. Besides Abbott and Costello, the studio retained the Walter Lantz cartoon studio, whose product was released with Universal-International's films.

Document 4: Power Rangers: Saban Entertainment distributed the Power Rangers series from 1993 until the end of 2001, and Fox broadcast it until the fall of 2002. The Walt Disney Company purchased the franchise as part of a buyout that took place in 2001. This resulted in Fox Family Worldwide becoming ABC Family Worldwide Inc. This buyout also saw Saban Entertainment becoming BVS Entertainment in 2002, from News Corporation, Fox's parent company, and Haim Saban. The show continued to air on Fox until the company replaced its Fox Kids package with ``FoxBox ''in the United States. Since September 2002, all Power Rangers shows had aired on various Disney - owned networks (ABC Kids, Toon Disney and Jetix channels worldwide). When Wild Force ended, Disney moved production of the franchise from Los Angeles to New Zealand. This resulted in the closure of MMPR Productions and the dismissal of many members of the production. From Ninja Storm to date, Power Rangers is produced in New Zealand. ABC Family, another Disney - owned network, also used to air Power Rangers until it did away with its Jetix timeslot after August 31, 2006. On February 12, 2009, Toon Disney ended in the wake of Disney XD, ending cable airings of Power Rangers in certain areas of the United States. Several ABC affiliate broadcasting groups declined to air most of the Power Rangers series since 2006 due to the lack of FCC - compliant educational and informational content in the programs.
