We are a Siemens Technology Solutions Partner and I just did a skim of the 20,000+ some odd pages of technical documentation related to Simatic, Simotion, Sinumerik, Simocrane products - (the wonder of computers) . . . not one mention of Ampere or Volta in the bunch. Many mentions of Amps (more often amps), and Volts / volts. Your observation of proper names and attribution is great in theory but abysmal in practice.
Language continues to change, roots of words forgotten, and time marches on. Not a mistake, no disrespect intended . . . it has and will continue to devolve with people depending more and more on jet-skiing over information with Google rather than doing a deep dive into a good book. In this case, I think you jumped the shark with this observation.
BTW - I spent quite a bit of time in my early engineering career working near Wildegg Switzerland . . . I was a Field Engineer for a TBM boring the Bözberg Tunnels and as I recall we fed the machine with a pair of 2000 kVA transformers. Beautiful country.
