In 1939, the Dongs, a Chinese American family, could not find a house to rent in Coronado, Calif., because of racially restrictive housing laws. Emma and Gus Thompson, a Black couple, allowed the family to rent and later buy their home. Now, the Dongs have sold that house, and are donating $5 million to Black college students. They are also working to have San Diego State University's Black Resource Center named after Emma and Gus, who was born into slavery in Kentucky. Here's more from NBC News.
