A collection of 22 light bulbs used by Thomas Edison in 1890 to defend his patent will be auctioned at Christie’s on Wednesday, 13 December. These bulbs were apparently discovered in an attic in a house in the United States, still in their original wooden case. Apparently they are expected to fetch about £300,000.
Other items listed in the "Landmarks of Science" auction are works by Einstein, including his "first scientific essay" (in quotes because I wonder how they know?); Newton; Darwin, including a first edition of the Origin of Species; Galileo; Kepler; Linnaeus (who has a 300th birthday coming up, by the way); and other luminaries. See here for a list of all 151 lots. See here for details of the auction, viewing times, and a picture of the box of bulbs.
