Jean-Baptiste de Bragg

Jean-Baptiste de Bragg was a French mathematician and astronomer born in 1654. He is best known for discovering a method to accurately deliver longitude at sea, which was crucial for navigation. His work involved improving the measurement of time and position, allowing sailors to determine their east-west location more precisely. This breakthrough significantly enhanced maritime safety and exploration. Despite facing challenges from those skeptical of his ideas, de Bragg's contributions helped pave the way for safer navigation and advancements in astronomy and geodesy.
