Fifty years ago last weekend, civil-rights workers James Earl Chaney, Andrew Goodman, and Michael Schwerner were shot and killed by members of the Ku Klux Klan, including a deputy sheriff, in Philadelphia, Mississippi. Next Wednesday marks the 50th anniversary of the passage of the Civil Rights Act of 1964, one of the monumental achievements of the 20th century. Three weeks ago, on June 7, we had the 16th anniversary of the murder of James Byrd Jr. in Jasper, Texas, after he was chained to a pickup truck by white supremacists and dragged three miles, mostly while conscious, with his headless body thrown in front of an African-American graveyard. And Wednesday marked the first anniversary of Shelby County v. Holder, the 5-4 Supreme Court ruling written by Chief Justice John Roberts that eviscerated the Voting Rights Act of 1965. The story of the Civil Rights Act has been told vividly and wonderfully in two new books by journalists Todd Purdum (An Idea Whose Time Has Come: Two Presidents, Two Parties, and the Battle for the Civil Rights Act of 1964) and Clay Risen (The Bill of the Century: The Epic Battle for the Civil Rights Act). Purdum brought his book to life a week ago in a talk at the Aspen Institute, weaving the remarkable tale of the miraculous passage of the bill—miraculous not so much in the fact that a bill made it through the labyrinth of the legislative process (after all, we had seen a weak and watered-down civil-rights bill pass in 1957), but that it was a strong bill. Many heroes inside and outside government made it happen. Lyndon Johnson was a towering figure, as were Hubert Humphrey, Martin Luther King Jr., A. Philip Randolph, and others in the civil-rights movement. Joe Rauh and others in the liberal community were also key players, and labor and the faith community were vital as well.
