Jean-Louis Pons
Jean-Louis Pons (24 December 1761 – 14 October 1831) was a French astronomer. Despite humble beginnings and being self-taught, he went on to become the greatest visual comet discoverer of all time: between 1801 and 1827 Pons discovered thirty-seven comets, more than any other person in history.
== Early life ==
Pons was born at Peyre, Hautes-Alpes, to a poor family; he received little formal education. In 1789, he began working for the Marseille observatory as a caretaker, and gradually gained some experience in assisting the astronomers with observations. He learned to make observations himself, showing a remarkable ability to remember star fields and note changes in them.
In his early astronomical career, the unassuming and trusting Pons was often the target of jokes perpetrated by more experienced astronomers. Franz Xaver von Zach once advised him to look for comets when sunspots were visible, though in doing so Zach may have inadvertently given Pons very good advice.〔Calder, N. ''Comets: Speculation and Discovery'', Courier, 1994, p.80〕
