Philip Dray

In There is Power in a Union: The Epic Story of Labor in America, journalist Philip Dray follows the labor movement as it grew out of 19th century uprisings in textile mills. There are several parallels between those historical battles and what is currently going on in Wisconsin, he says.

Author Philip Dray is the author of the book, At the Hands of Persons Unknown: The Lynching of Black America. Dray chronicles lynching. He looks at the perpetrators, the groups and individuals who courageously took a stand against it (the NAACP, Ida Wells, and W.E.B. Du Bois) and the legacy it left behind. Dray researched his book at the Tuskegee Institute where records about lynchings have been kept from 1882. He is also the co-author of We Are not Afraid: The Story of Goodman, Schwerner, and Chaney and the Civil Rights Campaign for Mississippi.

Authors Seth Cagin and Philip Dray. Their new book is "Between Earth and Sky: How CFCs Changed Our World and Endangered the Ozone Layer." It's about how CFCs (or chlorofluorocarbons) went from being the "miracle compound" to the the biggest threat to the ozone layer. CFCs came into being in 1928 and made possible the mass use of refrigerators and air conditioners. By the 1950s they were used in aerosol sprays and in the manufacture of Sytrofoam. But by 1974, scientists began to see their deleterious environmental effects.
