Most of that was WRONG, so I will give you the halfway real genesis instead, and then Axel Eichendorf or some ammunition specialist from the IAA forum may add the REAL real genesis to it. ;-)

This famous "pencil cartridge" was developed in the ambit and under the aura of famous Prussian and Imperial grand master of shotgunning and ballistics Albert Preuß. He had assembled a small group of enthusiasts who regularly met, once or twice a year, at a "Ballistischer Congress", and who of course corresponded assiduously in the meantime. Ammunition manufacturers, dealers, gunsmiths, ballisticians, one or the other officer, and also talented amateurs (dilettanti, in the positive sense). The latter were usually foresters or "gentlemen of independent means", who indulged in such noble pastime.
The longer biographic story of Preuß is rather hidden (!) here:

In our case, it was the interested and curiously-minded manor owner (Gutsbesitzer) Alfred Ungewitter, on Roßdorf manor near (Raguhn-)Jeßnitz. The next big city is infamous Bitterfeld. There are two Roßdorfs, not even far apart, and this one is *NOT* the one with the famous park and maze. Actually, the still extant "manor house" is a rather minor and modest building:





on the grounds of a former Eisenhammer (hammer forge or iron hammer); the small street still bears this old name.



The 6,5x70R was smokeless since its ineption, which is situated in the first years of the 20th century, probably between 1911/12, when Ungewitter seems to have interested Sauer & Sohn in a collaboration. The first ammunition manufacturer to produce it seems to have been Georg Roth (in Preßburg / Pozsony, in the Hungarian part of the double monarchy) . The cartridge was no doubt discussed and described in the two journals "Schießwesen" and "Schuß und Waffe" at the time.
