A deeper look at the legendary jazz musician’s work and thoughts on race in America:

Armstrong chose his battles carefully. In September, 1957, seven months after the bombing attempt in Knoxville, he grew strident when President Eisenhower did not compel Arkansas to allow nine students to attend Little Rock Central High School. As Teachout recounts in “Pops,” here Armstrong had leverage, and spoke out. Armstrong was then an unofficial goodwill ambassador for the State Department. Armstrong stated publicly that Eisenhower was “two-faced” and had “no guts.” He told one reporter, “It’s getting almost so bad a colored man hasn’t got any country.” His comments made network newscasts and front pages, and the A.P. reported that State Department officials had conceded that “Soviet propagandists would undoubtedly seize on Mr. Armstrong’s words.”

Doing things Armstrong’s way, no one had to accept responsibility for his actions but Louis Armstrong. When Eisenhower did force the schools to integrate, Armstrong’s tone was friendlier. “Daddy,” he telegrammed the President, “You have a good heart.”
