Edgar O. (Ed) Schmued

Edgar O. (Ed) Schmued (Schmüd), German-American aircraft designer (1899–1985) was famed for his design of the iconic North American P-51 Mustang and, later, the F-86 Sabre while at North American Aviation. He later worked on other aircraft designs as an aviation consultant.

Edgar Schmued was born in Hornbach, Germany, 30 December 1899. At the age of eight, he first saw an airplane in flight and decided that aviation was to be his life's work. Edgar embarked early on a rigorous program of self-study to become an engineer, and later served an apprenticeship in a small engine factory. He also designed several innovative engine components for which he received patents. In his spare time, he continued the self-study of aviation. Schmued left his native Bavaria for Brazil in 1925, seven years after World War I had shattered the German economy. 

His experience in Germany led to employment with the General Aviation, the air branch of General Motors Corporation in Brazil. In 1931, he was sponsored to move to the United States through his excellent work for General Motors in Brazil (immigration rules were extremely strict at that time - he was one of 794 people admitted in the quota) and went straight to work for Fokker Aircraft Corporation of America, which was an aircraft company that was owned by General Motors and based in New Jersey. There he began his career as an aircraft design engineer. General Motors later sold its air arm and it became the forerunner of North American Aviation.

The talented and inventive Schmued, by now a citizen of the United States, was employed by North American Aviation (NAA) in Dundalk, Maryland. In 1935, North American was relocated to Los Angeles, California, from General Motors. When his wife Luisa proved reluctant to relocate from the east coast, Schmued joined Bellanca but his time there was short-lived. While traveling to California to work again for North American, the Schmueds were involved in a head-on collision on Route 60. Schmued's wife was killed, while he himself was seriously injured.

North American Aviation
After recovering, Schmued went to work for "Dutch" Kindelberger in early 1936 as a preliminary design engineer. He was involved in the XB-21 (designing the front turret), creating the NA-50 single-engine fighter for Peru then going on to design work on the NA-62 (later the B-25 Mitchell). Schmued later became Chief of Preliminary Design.

During his long tenure at NAA, Schmued contributed greatly to the design of many airplanes. By far his most famous design was the highly successful P-51 Mustang of World War II. The legend began with NAA's President, "Dutch" Kindelberger asking, "Ed, do we want to build P-40s here?" Schmued had been long awaiting a question like this. His answer began the design process, "Well, Dutch, don't let us build an obsolete airplane, let's build a new one. We can design and build a better one." 

His adaptation of the then new laminar flow wing and other innovations made the P-51 performance outstanding in all respects and its flying qualities superb. This aircraft was still winning races and setting speed records for piston engine-powered airplanes decades after its production had ended. Although he was renowned as a workaholic at North American, Schmued undertook the design of the Morrow Victory Trainer in 1941 on an independent contract; it was dubbed the "Mini-Mustang" because of its close resemblance to the P-51.

Fueled by a striking similarity of the early Mustang and the German Messerschmitt Bf 109 - pilots and ground crews of both sides confused the two aircraft - and Schmued's German origin, an urban legend has grown up, claiming he had once worked for Willy Messerschmitt and that the Mustang was heavily influenced by the Bf 109. Neither claim is true but the urban legend persists. 

Schmued's team at NAA did receive, disassemble and inspect the first captured Bf 109 from the Spanish Civil War in 1939, and he regularly received copies of German Aeronautical Engineering Journals through 1941 supplied by Jim McGowan, ALCOA's consulting sales engineer. Just as familiar is the notion that the abortive Curtiss XP-46 was the basis of the P-51 design.

Schmued was employed by North American Aviation, later a division of the Rockwell International Corporation, for 22 years. During his tenure, Schmued also designed the F-82 and, the other iconic NAA designs, the F-86 Sabre and F-100 Super Sabre.

Northrop and later years
After leaving North American in August 1952, Schmued spent five years as Vice President of Engineering for the Northrop Corporation. At Northrop he recruited a top engineering team he used to develop the successful F-5 supersonic light fighter and the closely related T-38 trainer. 

For these aircraft Schmued emphasized not only performance, but simplicity, safety, low cost, and long service life. The resulting F-5 was not only the most cost effective U.S. supersonic fighter, but likely also the most combat effective U.S. air-to-air fighter design in the 1960s and early 1970s. The well regarded and long lived F-5 and the 
T-38 aircraft remain in active service as of 2014. 

The F-5 serves as an adversary aircraft for the U.S. Air Force and Navy in fighter combat training, as well as a front line fighter in the air forces of more than 20 nations. The T-38 has served as the primary advanced/supersonic trainer for the U.S. Air Force for more than 50 years, a record unequaled by any other aircraft of this class.

Edgar Schmued continued his aircraft design work as an independent consultant following his retirement from Northrop in October, 1957. He consulted for the U.S. Department of Defense, allied nations, for private companies, and for the film industry making aviation related movies. He worked actively until shortly before his death on 1 June 1985.

Any damned fool can criticize, but it takes a genius to design it in the first place.
