I don't think there is one. In the field of technology, major breakthroughs occur all the time... Nobody has revolutionized firearms the way apple revolutionized personal technology devices. I'm not sure how anyone could.
I don't agree entirely- the difference is that firearms are a mature technology whereas computers and personal technology are still developing. There were numerous game-changing technical innovations in firearms design- they just came in the late 19th century!
IMHO computers and personal technology are probably where the firearms industry was in 1910 and the auto industry was in 1955; the basic fundamentals have been invented, so the new models aren't leaps and bounds better than the previous models from a sheer technical standpoint. However, a lot of refinements are reshaping what people expect the technology to do, and several substantial leaps forward are probably still on the way.
There isn't one. Jobs' following isn't because he's a good inventor. He has a great eye for design and is a genius at marketing, but the cult of personality around him just has no parallel in the firearms world.
+1.
Sam Colt was an inventor and a good promoter but he could not run a business very well.
John Moses Browning was a technical genius but he was content to stay in the shadows and let others manufacture his designs.
Hiram Maxim briefly approached Jobs' combination of marketing brilliance, business sense, and cult of personality, but refinements by others (including Browning) quickly surpassed his original invention, and he did not have anything up his sleeve to follow it.
Bill Ruger was ~40 years too late. Also, IMHO Ruger's genius is more comparable to Soichiro Honda- the ability to look at a complex and expensive product invented by others, strip it down to what buyers really want, leave off the extraneous fluff, and sell it cheaper than anyone else can.
