Julius Rosenburg is an obvious one. The Nazis executed gobs of scientists. And I'm certain I could find other examples if needed, but that is off the top of my head.
The National Socialists were socialists so that undermines not reinforces your point:
- they implemented communist policies like mass nationalization schemes with some of the resulting "companies" being amongst the largest organizations in the world
- they wanted to fully nationalize the entire economy after the war
- they passed large amounts of left wing legislation
- they, obviously, called themselves socialists constantly. Hitler said "I am a fanatical socialist".
- they openly hated capitalism. A big part of their hate for Jews was that they associated Judaism with international capital. Same reason Marx was an anti-semite.
