>>20424501Listen, retard. The first ballpoint patent wasn't a pen that could be used with paper as the writing medium, it was for marking on wood and leather and wouldn't reliably put ink down on paper or would shred it to pieces. It didn't have a ton of uses and the patent lapsed without it being commercially successful.
It wasn't until 1938 that a patent was filed for one that could be used with paper, and it was some Hungarian guy whose name I can't remember. The plans to produce this patented pen were put on hold by WW2, and it wasn't until post-war that the inventor managed to actually mass-produce the thing and license it out to other companies so it could become ubiquitous, and for the first several years it was an expensive luxury item. For the point that you're getting to, it was essentially an impossibility that some jewish teenager had her little jewish claws clasping a ball point pen of any kind in the early 1940s, since the disposable and cheap ones didn't come out until the 1950s and enter into mass use until the 1960s.
