Donald Sewell Lopez (1923-2008) joined the staff of the Smithsonian Institution in 1972 as part of the team responsible for planning the construction and opening of the National Air and Space Museum (NASM). As assistant director for Aeronautics, Lopez was instrumental in developing the exhibits that welcomed visitors at the museum's opening on July 1, 1976. Lopez became deputy director of NASM in 1983, a position he held until 1990. He served as senior advisor to the director before retiring in 1993, holding a position as senior advisor emeritus until he was again appointed deputy director in 1996, a position he held until his death. Before coming to the Smithsonian, Lopez was already an aviation legend: he was a fighter pilot in the 23rd Fighter Group of the 14th Air Force - successors of the legendary Flying Tigers - in China. He flew Curtiss P-40s and North American P-51 Mustangs, demonstrating his extraordinary flying skills under the leadership of famous war heroes Col. Tex Hill and Gen. Claire Chennault. During his two years in China, Lopez flew 101 missions and tallied up five victories, the required number to be recognized as an "Ace." Lopez was awarded the Silver Star, Distinguished Flying Cross, and three Air Medals for his service during World War II. After the War, Lopez became an Air Force test pilot and then served in combat again during the Korean War flying North American F-86s. Lopez then served at the Pentagon, during which time he also earned a bachelor's degree in aeronautical engineering at the Air Force Institute of Technology and a master's degree in aeronautics from the California Institute of Technology. Lopez served at the US Air Force Academy as an associate professor of aeronautics and chief of academic counseling before retiring from the US Air Force in 1964 at the rank of lieutenant colonel. Lopez then worked as a Systems Engineer on the Apollo-Saturn Launch Vehicle and the Skylab Orbital Workshop for Bellcomm, Inc. Lopez was a member of the American Fighter Aces Association, the Experimental Aircraft Association and was a Fellow of the Royal Aeronautical Society. Lopez was the recipient of many honors and awards, including being named an Elder Statesman of Aviation by the National Aeronautic Association (1995); the Federal Hispanic Heritage Month Excellence in Leadership Award recipient (1999); the Frank G. Brewer Trophy in Museum Education recipient; being inducted as a fellow by the Society of Experimental Test Pilots (2006); and being honored as one of the living legends at the Gathering of Mustangs and Legends at Rickenbacker Field in Columbus, Ohio (2007). Lopez's publications include Into the Teeth of the Tiger (Bantam, 1986), The National Air and Space Museum: A Visit in Pictures (Smithsonian Institution Press, 1989) and Fighter Pilot's Heaven: Flight Testing the Early Jets (Smithsonian Institution Press, 1995).
