Walter Thiel (March 2, 1910 - August 17, 1943) was a German engineer who largely designed the rocket engine that powered the V-2 missile. He joined Wernher von Braun's team at Peenemünde in 1936 and provided the breakthrough that made the V-2 possible when he decided to use turbopumps to feed fuel into the rocket engine. Thiel's refinement led to a tenfold increase in power.
