"The history books, which had almost completely ignored the contribution of the Negro in American history, only served to intensify the Negroes' sense of worthlessness and to augment the anachronistic doctrine of white supremacy. All too many Negroes and whites are unaware of the fact that the first American to shed blood in the revolution which freed this country from British oppression was a black seaman named Crispus Attucks. Negroes and whites are almost totally oblivious of the fact that it was a Negro physician, Dr. Daniel Hale Williams, who performed the first successful operation on the heart in America. Another Negro physician, Dr. Charles Drew, was largely responsible for developing the method of separating blood plasma and storing it on a large scale, a process that saved thousands of lives in World War II and has made possible many of the important advances in postwar medicine. History books have virtually overlooked the many Negro scientists and inventors who have enriched American life. Although a few refer to George Washington Carver, whose research in agricultural products helped to revive the economy of the South when the throne of King Cotton began to totter, they ignore the contribution of Norbert Rillieuz, whose invention of an evaporating pan revolutionized the process of sugar refining. How many people know that multimillion-dollar United Shoe Machinery Company developed from the shoe-lasting machine invented in the last century by a Negro from Dutch Guiana, Jan Matzelinger; or that Granville T. Woods, an expert in electric motors, whose many patents speeded the growth and improvement of the railroads at the beginning of this century, was a Negro?Even the Negroes' contribution to the music of America is sometimes overlooked in astonishing ways. In 1965 my oldest son and daughter entered an integrated school in Atlanta. A few months later my wife and I were invited to attend a program entitled "Music that has made America great." As the evening unfolded, we listened to the folk songs and melodies of the various immigrant groups. We were certain that the program would end with the most original of all American music, the Negro spiritual. But we were mistaken. Instead, all the students, including our children, ended the program by singing "Dixie"."
