Standing on their lawn, members of the Dong family waited to meet the great-grandkids of a Black couple, the Thompsons, who rented a home to them a generation ago, when laws favored white residents. The Dong family is now selling the historic home and donating $5 million to Black college students — but they wanted the Thompson family to tour the storied home first. After the tour the two families headed to a dedication ceremony to name San Diego State University’s Black Resource Center after Emma and Gus Thompson, who was born into slavery in Kentucky. The $5 million gift will be used to enhance the center’s academic efforts, grow its mentorship program, advance support for mental health and upgrade facilities, said Christopher Manning, SDSU’s vice president for student affairs and campus diversity. 📷 alannakkash for nbcnews
