This is "Grandma Mary Erben" of Wisconsin. Other than that little bit of information, all I know about this pleasant soul is in the photograph.

Her biggish wheel is an upright double drive with a flat rim on the drive wheel. She has a good supply of washed wool close at hand and has just started a new bobbin. She has a tuft of wool in her left hand, but there's no sign of combs or hand cards. Perhaps she just teases the wool out by hand and spins from that.
Take a look at the very interesting kate in the lower right-hand corner.
Finally, I like that her family thought enough of her that they had the photograph professionally mounted. And so she was preserved for us.
I kind of wish she were my grandma, but she was someone's grandma.
