Carl Bleicher 1A - 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, any information someone has
