Carl Bleicher 1B - 1801

So I found a bunch of Photos hidden in an Album, but they are not labeled.

Does anyone Recognize this man? I have 5 photos that were found together of what appears to be the same family. I am not sure how they connect to my family.

You can find the back of the photo under Carl Bleicher 1A/1B.

They were in my Grandma's Album.

I'm hoping someone can help tell me anything about them.

Who is he, does he connect to the group, and any other information someone has
