Houtermans was working for the German post office and his work
consisted of writing a report stating a reactor could produce plutonium

Houtermanns was the associate of von Ardenne.(BTW von Ardenne was the person
who saved from Gestapo)


in Cambridge. The difference is that the Anglo-American team
were able to build a working reactor and produce plutonium
rather than just talking about it.



Houtermanns was pionier in producing Plutonium using Chemical process.
In 1942 they were already producing Plutonium in Klein-Machow whereas
Anglo-American Manhattan Project in March 45 neither produced enough Uran nor
Plutonium and that was the reason why some powerful Congressmen called for its
termination.

Thats one of the the differences between German and Manhattan projects,one by
taking advantage of famous German innovative abilities produced results even
with very limited resources,while the latter stalled in early 1945 inspite of
colossal resources committed to the project.
