J. Edgar Hoover

I would highly recommend Beverly Gage's new biography of Hoover. People from many legal disciplines will find this book useful given the FBI Director's broad reach and skill at institution building. There is also great stuff in the book on a host of specific issues. For example, I was unaware that there was a detention of some German-Americans during World War I that was a forerunner of what was done to Japanese-Americans in World War II (and explains why Hoover opposed Japanese-American internment).
