Earlier quoted context omitted.
Just the building, not the entire CSE department. Not to mention Allen library.
The library was named for Kenneth S. Allen, Associate Director of Libraries from 1960 to 1982, in recognition of his years of service to the Libraries, and in appreciation of a generous gift from his son, Paul G. Allen, co-founder of Microsoft. http://www.lib.washington.edu/suzzallo/visit/about
I went to UW in the 90s when Allen library was brand new and the new CS building was just a dream.
