I'm proud to announce the online publication of an essay commissioned by the World War II Museum for their website, "The Origins of 'Cool' in Post-WWII America." There are new aspects of my work here, including anti-racism, etymology, the cultural politics of jazz in the Cold War, and why jazz transformed from "hot music" into cool music. Postwar authors Ralph Ellison and Simone de Beauvoir help guide the ride through the usual postwar cool suspects: Miles Davis, Sinatra, Lester Young and Billie Holiday, Bogart, Ellington, The Beats, Elvis. This is the most accessible (and free!) cool essay of mine on the internet. Thanks to the good folks at the WW2 Museum for the opportunity.
