I want to know the answer to the following question:
What engineer was recruited by Becker and Dornberger to join their secret program?
All the background I'm provided with is that "The head of the German Army's Ballistics and Munitions Branch, Lieutenant Colonel Karl Emil Becker, gathered a small team of engineers that included Walter Dornberger and Leo Zanssen, to figure out how to use rockets as long-range artillery in order to get around the Treaty of Versailles' ban on research and development of long-range cannons.". Is that enough to answer the question?
