拍品專文

Heinrich Kessels (1781-1849) was born in Maastricht, The Netherlands, then a city of the French Empire. He worked for Breguet in Paris. In 1821 he went to Copenhagen, receiving the patronage of King Frederich VI, who encouraged him to stay in Altona, then Danish territory. Chronometer maker to the Danish Navy and a member of the Swedish academy, he sold instruments to most of the north European observatories.
