Life and work Jecker was born in Hirtzfelden near Colmar, Haut-Rhin, the son of a farmer. His brother Laurenz Jecker (1769–1834) became a needle manufacturer. He apprenticed with a watchmaker in Besançon where two uncles worked as musicians. He went to London in 1786 and trained with Jesse Ramsden and returned to Paris in 1792 where he started a workshop to manufacture astronomical instruments and precision measuring instruments. He was joined by his brothers Gervais and Protais and by 1800 he had nearly 40 employees.
