Professor Oppenheimer discusses his new book about the two-hundred-year history of diversity in education, commerce, and science.

As the war on diversity upends government, corporate and education policies, the history of the idea of diversity has never been more important. David Oppenheimer, a diversity skeptic turned diversity admirer, chronicles how diversity became a foundational value of higher education over the last 200 years, how it evolved as it was adopted by commerce and science, and what the implications are of the current backlash.
