13956 Banks           Discovered 1990 Nov. 15 by E. W. Elst at the European Southern Observatory.
British botanist Joseph Banks (1743-1820) joined James Cook on the Endeavour. He proposed an experiment to move en masse a food crop (namely, breadfruit) from one location to another. The first mission, under the command of Captain Bligh, was doomed to fail, but the second in 1791 was successful.
