I want to know the answer to the following question:
Which theater company was founded by several Northwestern alumni in 1988?
All the background I'm provided with is that "Chicago's Lookingglass Theatre Company, for example, which began life in the Great Room in Jones Residential College, was founded in 1988 by several alumni, including David Schwimmer; in 2011, it won the Regional Tony Award.". Is that enough to answer the question?
