Helmut Hoelzer[1] was a Nazi Germany V-2 rocket engineer who was brought to the United States under Operation Paperclip.


In October 1939, while working for the Telefunken electronics firm in Berlin, Hoelzer met with Ernst Steinhoff,[2] Hermann Steuding, and Wernher von Braun regarding guide beams for a flying body.[Neufeld 1] In late 1940 at Peenemünde, Hoelzer was head of the guide beam division[Neufeld 2] (assistant Henry Otto Hirschler[3]), which developed a guide-plane system which alternates a transmitted signal from two antennas a short distance apart, as well as a vacuum tube mixing device (German: Mischgerät)[4] which corrected for momentum that would perturb an object that had been moved back on-track.[Neufeld 3] By the Fall of 1941, Hoelzer's "mixing device" was used to provide V-2 rocket rate measurement instead of rate gyros.[Neufeld 4]

Then at the beginning of 1942, Hoelzer built an analog computer to calculate and simulate[3] V-2 rocket trajectories[Neufeld 5][5] Hoelzer's team also developed the Messina telemetry system.[6] After evacuating Peenemünde for the Alpenfestung (Alpine Fortress), Hoelzer returned to Peenemünde via motorcycle to look for portions of his PhD dissertation[1] prior to surrendering to United States forces at the end of World War II.


One of his grandchildren is Olympic swimmer Margaret Hoelzer.
