11021 Foderà           Discovered 1986 Jan. 12 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Giorgia Foderà (b. 1942) teaches history of astronomy at Palermo University. Curator of the Palermo Observatory museum, she published the inventory of its instruments, which include the vertical circle used by Piazzi. She was the principal organizer of the Palermo Observatory's celebration of Ceres' bicentennial.
