During World War II, students from the University of Maryland taught several classes, and in some cases, able senior students taught sophomore classes. The Blair Library created the "Senior Corner" to honor those who had not returned from war. Life Magazine featured the school's Victory Corps close order drill team. Prior to the Supreme Court decision in Brown v. Board of Education, Blair was an all-white school. In 1955, the school began to integrate along with the rest of Montgomery County.
