Werner Karl Dahm (born February 16, 1917, in Lindenthal, Germany – died January 17, 2008, in Huntsville, Alabama) was a brilliant scientist who helped create rockets and spacecraft. He was an expert in aerodynamics, which is the study of how air moves around objects. This knowledge is super important for designing rockets and planes.
Werner Dahm worked at the Peenemünde Future Projects Office in Germany. After World War II, he moved to the United States as part of Operation Paperclip. This was a special program that brought German scientists to the U.S. to help with their rocket development. Later, he became the Chief Aerodynamicist at NASA's Marshall Space Flight Center, playing a key role in America's space program.

Early Life and Education
Werner Karl Dahm was born in Lindenthal, Germany, on February 16, 1917. His family moved to Bonn later that same year. His father was an engineer, which was a new path for their family of merchants.
After finishing school in 1936, Werner studied aerodynamics and aircraft design. He attended the Technical University in Aachen and later the Munich. He focused on rocketry because of political issues at the time.
Joining the Rocket Team
In 1939, Werner was drafted into the military. He served in a signal corps unit in France and Czechoslovakia. He was allowed a short break to complete most of his aerodynamics degree.
Because of his technical skills, he was assigned to the German rocket development team in late 1941. This team was led by Wernher von Braun at Peenemünde. Werner was the youngest member of the future projects division.
Pioneering Rocket Science
At Peenemünde, Werner worked on understanding high-speed aerodynamics. This field was very new at the time. He helped conduct important experiments in a small supersonic wind tunnel. These tests provided key information for designing new rockets.
Solving Stability Challenges
One major project was the A9/A10 rocket. This rocket was designed to be the first intercontinental ballistic missile. It was a winged version of the V2 rocket, meant to fly very fast.
Werner discovered a problem: the rocket would become unstable when it reached supersonic speeds. This happened because the "center-of-pressure" shifted. He worked on experiments and theories to fix this. His goal was to make sure the rocket stayed stable during flight.
He also worked on the Wasserfall rocket, which was a radar-guided anti-aircraft missile. This rocket had the same stability problem. Werner even designed a special fuel tank that prevented liquid fuel from sloshing around.
In 1943, Allied forces bombed the Peenemünde facilities. Werner was praised for saving important wind tunnel data during the fires. The Wasserfall project continued, and the rocket flew successfully, but it was never mass-produced.
Final German Rocket Tests
In 1944, Werner and his team resumed work on the A9/A10 rocket. In January 1945, two A9 test rockets were launched. Their control surfaces were designed using the team's solution to the center-of-pressure shift. The second test rocket successfully transitioned to stable supersonic flight.
Moving to the United States
As World War II ended, Werner and most of the rocket team moved to Oberammergau. They wanted to surrender to American forces. After his release in August 1945, Werner worked briefly in a candle factory.
Soon after, he was invited to join the U.S. rocket program as part of Operation Paperclip. However, he insisted on finishing his degree first. He officially earned his degree in mechanical engineering. In August 1947, he joined other scientists from von Braun's team at Fort Bliss, Texas.
Contributions to U.S. Rocketry
In the U.S., Werner first worked on tests using V2 rockets at White Sands Missile Range. These tests were crucial for developing the Redstone rocket. The Redstone rocket later launched the first U.S. astronaut into space.
He also worked on the Hermes II, a Mach 3 cruise missile. In 1950, he moved to Huntsville, Alabama, with the von Braun team. There, he designed the outer shape of the Army's Redstone missile.
Werner also developed a successful nose cone for ballistic re-entry at Mach 5. He did this using only theory, as there were no hypersonic wind tunnels to test his ideas. He continued to make important contributions to other missile programs, like the Jupiter and Pershing missiles, and the large Saturn I booster rocket.
NASA and Space Exploration
After the Soviet Union launched Sputnik, Werner and other scientists moved from the Army Ballistic Missile Agency to the new NASA in 1960. He played a major role in the Apollo moon-landing program. He worked on the Saturn V booster rocket, which sent astronauts to the Moon.
He also contributed to projects like Skylab and the Space Shuttle. For the Space Shuttle, he led a team working on vehicle aerodynamics and the main engines. His team developed tests and used computer models to solve complex problems.
Werner Dahm was Chief of the Aerophysics Division at NASA's Marshall Space Flight Center until 1992. Then, he became the Chief Aerodynamicist for the entire NASA Center.
Awards and Legacy
In 1997, he received the AIAA Aerodynamics Award. This award recognized his amazing contributions to designing rockets and missiles throughout his life. In 2003, he was awarded the NASA Exceptional Service Medal.
Werner Dahm continued working at NASA until he retired at 89 years old in 2006. David King, the director of NASA's Marshall Space Flight Center, praised him. He said, "America's space program is preeminent because folks like Mr. Dahm contributed to building it into the best in the world. His life and life's work are an example of his energy, dedication and humble leadership, which has played a significant role in humanity's peaceful use of space."
Werner Dahm also held patents for inventions like a Wind Measurement System, a Focused Laser Doppler Velocimeter, and a Clean Air Turbulence Detector.
