 His mural, "The Apotheosis of St. Louis", that adorned the St. Louis Board of Education assembly room had featured only white children.In light of the controversy of racial integration in St. Louis public schools, Nuderscher volunteered to repaint two of the children in the mural to be African-American and thus integrate the mural in a symbolic act.According to art historian William H. Gerdts, Nuderscher "was the most significant Impressionist painter to spend his whole career in Missouri."
