Christie’s withdraws rare ‘first calculator’ from auction after French court halts export

Move comes after French scientists issued urgent appeal to prevent La Pascaline from leaving the country

A rare example of the first functioning calculating machine in history looks likely to stay in France after Christie's withdrew it from auction pending a definitive ruling from a Paris court on whether or not it can be exported.

La Pascaline, developed by the French mathematician and inventor Blaise Pascal in 1642, when he was just 19, and billed as the most important scientific instrument ever offered at auction", had been expected to fetch more than 2m (1.8m).
