Eric Schlosser, author of “Fast Food Nation: The Dark Side of the American Meal,” will deliver the commencement speech for the class of 2012.

Schlosser is also the author of “Reefer Madness: Sex, Drugs and Cheap Labor in the American Black Market,” a 2003 book on the history and trade of marijuana, labor conditions of migrant workers and the pornography industry. Schlosser’s investigative journalism has appeared in many national publications including The Atlantic Monthly. He received a National Magazine Award in 1995 for his magazine article, “Reefer Madness,” and is currently working on a book, “Command and Control,” about the state of nuclear threats.

“It’s an honor to be giving the Commencement speech at Whitman this year,” said Schlosser in a Whitman College press release. “During my previous visits to the campus, I found the students really impressive and their commitment to sustainability encouraging. I think Whitman is a real gem.”

Commencement takes place on May 20 at 11 a.m.
