That’s the question being asked about an atom sculpture on the U of M Morris (UMM) campus. 

It belonged to Professor Jim Gremmels and his wife, Ruth, who kept it in their front yard. Their son, Paul, and his wife, Ann, donated it to UMM in the elder Gremmels’ memory.

“My dad said he traded the guy an old canoe for the piece,” says Paul, who has been trying to learn the identity of the artist in this 1972 photo. Got a clue? Contact Jeff Lamberty at lamberjj@morris.umn.edu.
