213269 Angelbarbero           Discovered 2001 June 20 at Calar Alto.
Angel Barbero Peregrina (b. 1972) worked from 2004 until 2014 as a chef at the Spanish Calar Alto Observatory. Through his culinary skills he contributed significantly to the well-being of his fellow colleagues, visiting astronomers, and the discoverers of this asteroid. He and his food are dearly missed.
