In 1798 he served as the Swiss representative to the French metric convocation, and was a member of its committee on weights and measures. An iron "committee" meter, a duplicate of the prototype archive meter, was then given as a gift to Ferdinand Rudolph Hassler. From 1803 until 1805 these two men worked together on a topological survey of the Canton of Bern.
In 1819, he discovered the Great Comet of 1819, Comet Tralles, named after him.[1]
He was the inventor of the alcoholometer, a device for measuring the amount of alcohol in a liquid.
He died in London, England. The crater Tralles on the Moon is named after him, as is the alcoholometer he invented.
