I read through the rules, and I think (I hope) I can ask this question here to you /r/AskHistorians!

I did a search for "long nineteenth century Europe" in google images, and found a picture I would like to use, but I can't figure out who this guy is. Does anyone know?

If this is against the rules, I apologize! But I thought this would be the best place to find the answer. If there is a better subreddit, please let me know!

Here is the picture:
