Lady Bird Johnson (seen here second from the left), wife of President Lyndon B. Johnson, visited Southwestern Medical School on March 9, 1971. In this photo, she listens as Dr. Gunnar Blomqvist (on the right, in white lab coat) explains the effects of exercise. Also in the photo are Dr. Charles C. Sprague, Dean of Southwestern Medical School, and (on the far left), Mrs. Alice Fordyce, Lady Bird Johnson's friend. (Note: Dr. Blomqvist's last name is sometimes spelled "Blomquist".)
