Jean-Baptiste Joseph Delambre

Jean-Baptiste Joseph Delambre was a French mathematician and astronomer born in 1749. He played a key role in the late 18th and early 19th centuries by helping to measure the Earth's shape and size. Delambre worked on precise ground measurements that contributed to defining the meter, the standard unit of length used today. His meticulous efforts in surveying and mathematics improved our understanding of Earth's dimensions and established important foundations for science and navigation.
