This is from the June 5th 1897 edition of "The Electrical World" by John W. Howell who worked for Edison on the incandescent lamp. https://en.wikipedia.org/wiki/John_White_Howell
This article was his take on the "new" 220V lamps that were quickly being adopted in the UK. It's a fascinating piece that explains why 110 was chosen by Edison and why Europe decided on 220. There have been a lot of writings as how that happened, but here it is from an engineer that was there. I was surprised that there was a third standard, 55V.
I hope you find it informative. Genehttps://books.google.com/books?id=b...amp;pg=PA705#v=onepage&q&f=false
