Horace's son Horace R. Cayton Jr. (1903–1970) became an educator, researcher, government official, newspaper columnist, and famous sociologist, notable for his anthropological work "Black Metropolis", which he co-authored with St. Clair Drake. Lisa S. Weitzman says on Answers.com: "With the purpose of educating white America, the book further exposed and explained African American conduct, personality, and culture which emerged from the conditions imposed by the white world. Ultimately, Cayton and Drake concluded their book with a call for the government to work more aggressively to help African Americans achieve equality. Like his father, Cayton expressed an ongoing concern for racial equality and civil rights, a theme to which he repeatedly returned in his regular column for the Pittsburgh Courier."
