Albert Einstein, Lincoln University, 3 May 1946, as quoted by J. W. Woods, in "Lincoln U. confers degree on Einstein," Baltimore Afro American, May 11, 1946, p. 2, col. 5 (continued from p. 1, col. 5). No version of this statement appears in the "On race and prejudice" section (pp. 309 ff.) of Alice Calaprice's The ultimate quotable Einstein (Princeton University Press, 2010). Other versions:
"'There is separation of colored people from white people in the United States. That separation is not a disease of colored people. It is a disease of white people. I do not intend to be quiet about it.'"
As quoted by Fred Jerome and Rodney Taylor, in Einstein on race and racism (Piscataway, NJ: Rutgers University Press, 2005), 142, citing the Baltimore Afro American (above).
