12156 Ubels           Discovered 1973 Sept. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Egbert Ubels (1969-2008) was a fantastic father to Nick and Dagmar and the beloved husband of Sandra. He was a fireman through and through, who perished in his harness while trying to extinguish a huge fire. He will always be remembered by this special place in the sky.
