Yup, just like Steve Jobs inventing the iPod, IPhone, and IPad
"I am sure there are many others, but these were the ones that came to mind."
Probably because their names are funny-lookin', but Czech designers don't get nearly enough credit. First perfected LMG (ZB30 series), first perfected HMG (ZB37 series), first telescoping bolt SMG (ZB26 series), better alternatives to the AK and PK series (VZ58 and UK59), and even more basic technologies going back centuries before.
Dieudonne Saive, of FAL and Hi Power fame, was also a master, and then you have Johnson and Pedersen who managed to never get past the starving-artist phase to true stardom, despite a plethora of fantastic (and widely plagiarized) ideas.
The designers I am most impressed with at present are Arne Boberg and to a different extent, Kevin Brittingham of ACC for popularizing suppressors second only to Henry Maxim (a lot of this is perception, but he seemed to be the best known name way out in front of the current suppressor development wave, taking risks and staking claims). Boberg is basically doing the Tucker Car but with firearms, and without the legal/financial shenanigans. Created a novel design, teamed up with a shop to introduce it, and now promotes and stands behind it personally, to pretty much universal praise from owners. Even after hitting one home run, he continues to develop the brand and product line himself, and maintains surprisingly close contact with his market and existing customers so as to best suit their whimsy. Class act of a small business/man if I've ever seen one, and definitely deserving of patronage.
