This is from the June 5th 1897 edition of "The Electrical World" by John W. Howell who worked for Edison on the incandescent lamp.

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. Gene;pg=PA705#v=onepage&q&f=false
