An invention of the 19th Century

This idea seemed original when I researched it in error a week ago, but now I see that it is one of several this week.  The picture itself tells you who the inventor was and what he invented.  Unfortunately this is a Parker pen, not a Waterman but it is genuinely a fountain pen as opposed to a cartridge pen.  Many thanks to laurie54 for her most interesting themes this month.
In other news: nothing of significance today, although I did manage to get up the patio steps with only a stick for support, which is more of an achievement that one might imagine!
