11069 Bellqvist           Discovered 1992 Mar. 1 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
Sven Bellqvist (1915-2008) was for many years in charge of the workshop at the astronomical observatory in Uppsala. During this time the Schmidt telescopes at Kvistaberg and at Mount Stromlo Observatory were built.
