Task: Question Answering
Input (English): Passage: In 1959, Stafford was offered a contract to perform at Las Vegas, but declined it to concentrate on her family life. Because she disliked continuously traveling for television appearances that took her away from her children, and no longer found the music business fun, she went into semi-retirement in the mid-1960s. She retired fully in 1975. Except for the Jonathan and Darlene Edwards material, and re-recording  her favorite song "Whispering Hope" with her daughter Amy in 1978, Stafford did not perform again until 1990, at a ceremony honoring Frank Sinatra. The Westons devoted more time to Share Inc.—a charity aiding people with developmental disabilities—in which they had been active for many years. In or around 1983, Concord Records tried to persuade Stafford to change her mind and come out of retirement, but although an album was planned, she did not feel she would be satisfied with the finished product, and the project was shelved.Stafford won a breach-of-contract lawsuit against her former record label Columbia in the early 1990s. Because of a clause concerning the payment of royalties in her contract, she secured the rights to all of the recordings she made with the company, including those Weston and she made as Jonathan and Darlene Edwards. After the lawsuit was settled, Stafford and her son Tim reactivated Corinthian Records, which Weston—a devout Christian—had started as a label for religious music in the 1970s, and they began releasing some of her old material.In 1996, Paul Weston died of natural causes; Stafford continued to operate Corinthian Records. In 2006, she donated the couple's library—including music arrangements, photographs, business correspondence and recordings—to the University of Arizona. Stafford began suffering from congestive heart failure in October 2007, from which she died aged 90 on July 16, 2008. She was buried with her husband at the Holy Cross Cemetery in Culver City, California. 
Question: What is the name of the person who donated the couple's library to the University of Arizona?
