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.Naming citation (20090209/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
