Harvard awarded Chandler Davis a PhD in mathematics in 1950. Three years later, Davis was served with a subpoena as a result of his having paid for the printing of a pamphlet critical of the House Committee on Un-American Activities, and his subsequent ordeal included the loss of his job at the University of Michigan and a six-month imprisonment in 1960 for contempt of Congress. Blacklisted from full-time academic jobs in the US, he ultimately found employment in 1962 at the University of Toronto, where he is now an Emeritus Professor of Mathematics. It Walks in Beauty collects several of his science fiction stories, which probe deeply into such social and political issues as nuclear escalation, gender roles, and eugenics, as well as a selection of his essays, originally published in venues ranging from The New York Review of Books to the Waging Peace Series of the Nuclear Age Peace Foundation. The volume also includes a lengthy interview of Davis by Lukin, a speech Davis made at the February 1995 meeting of AAAS, as well as three essays by Lukin, taking a long view of Davis's work. H. Bruce Franklin writes ''Although Chandler Davis has published less than a score of science-fiction short stories, some of us have long treasured them as brilliant gems. Josh Lukin's thoughtful collection of Davis's fiction and nonfiction offers 21st-century readers a fine introduction to the work of this neglected and invaluable writer.''
