They had Rollerblades in 1862??

If you remember the fads of the 1990s you'll instantly recognize this invention. Not as new as you thought.

From "A Guide to Skating", 1862

Avoid the embarrassment of being seen learning to ice skate by skating around indoors and injuring yourself in the privacy of your own home!

I have no idea when roller skates themselves were invented or who first attached wheels to shoes; maybe this would be an interesting topic to research on someone else's blog.

So in-line skates are at least 150 years old...

I miss my Rollerblades.
