The essays collected in this book honor H. Chandler Davis (1926-2022), a University of Michigan faculty member who became a symbol of principled dissent when suspended and fired in 1954 for refusing to testify about his political affiliations to the House Un-American Activities Committee. Invoking academic freedom and First Amendment protection, Davis was convicted of contempt of Congress. He served six months in prison before moving to Canada, where he established himself as a brilliant mathematician, prolific writer, and ardent and much beloved advocate for justice. At a time when a new McCarthyism has come roaring back to threaten free inquiry everywhere, the 12 contributors to this book argue against censorship, the suppression of protest, the policed and surveilled campus, the self-silencing of "institutional neutrality," and other enemies of academic freedom. Also included in this volume is posthumously published work by Davis and by his late wife, the historian Natalie Zemon Davis, which reflects on the importance of facing, and not accepting, authoritarian threats. Inspired by Chandler Davis’ courage, integrity, and devotion to the struggle against oppression, injustice, and the persecution of speech, these essays offer crucial insights into the importance of defending intellectual independence, institutional autonomy, and the right to free expression.
