The University of Portland has received a challenge grant of $150,000 from the Maybelle Clark Macdonald Fund for the renovation of the school's library. The library renovation and rebuilding project began in May 2012 and is expected to cost $12.5 million.  

In 1958, Maurie Clark, Portland businessman and philanthropist, was the major benefactor when the university constructed a new library building on the same location it occupies today.

Maybelle “Middy” Clark Macdonald, Maurie’s sister, also gave to the university. Known for quiet charity, she created the Maybelle Clark Macdonald Fund in 1970 with the mission "to relieve the misfortune and promote the well-being of mankind." Today, it is one of Oregon’s largest foundations and over the years has directed $1.2 million to the library. Maybelle Clark Macdonald helped Holy Cross Father Richard Berg found a center and residence for poor people in Portland's Old Town.

In 1972, the UP library was named for Wilson W. Clark, the father of Maurie and Maybelle.
