    Captain Walter S. Diehl was a pioneer of aerodynamics and aircraft design. From 1918 until his retirement in 1951, he directed the Navy's work in aerodynamics and hydrodynamics. He was responsible for the funding, programs, and facilities of the Aerodynamics Laboratory. The author of the authoritative "Engineering Aerodynamics," he actively participated in and strongly influenced continuing advances in aerodynamics and hydrodynamics. Walter Diehl is credited with initiating action that led to establishment of the David W. Taylor Model Basin at Carderock, Maryland, the Aircraft Research Station at Chincoteague, Virginia, and the Navy's test flight unit at the Naval Air Station, Anacostia, D. C., which later developed into the U.S. Naval Air Test Center, Patuxent, Maryland.
