I want to know the answer to the following question:
Who is Northwestern's faculty member notable for being a Holocaust denier?
All the background I'm provided with is that "Notable faculty include 2010 Nobel Prize–winning economist Dale T. Mortensen; nano-scientist Chad Mirkin; Tony Award-winning director Mary Zimmerman; management expert Philip Kotler; King Faisal International Prize in Science recipient Sir Fraser Stoddart; Steppenwolf Theatre director Anna Shapiro; sexual psychologist J. Michael Bailey; Holocaust denier Arthur Butz; Federalist Society co-founder Steven Calabresi; former Weatherman Bernardine Rae Dohrn; ethnographer Gary Alan Fine;". Is that enough to answer the question?
Answer: yes
