Is Nicholas flamel real

I believe this is the person that Harry potters maker got the character from.

Nicolas Flamel (French pronunciation: [nikɔlɑ flaˈmɛl]) (early 1330-1418) was a successful French scrivener and manuscript-seller who developed a posthumous reputation as an alchemist due to his reputed work on the philosopher's stone.

According to the introduction to his work and additional details that have accrued since its publication, Flamel was the most accomplished of the European alchemists, and had learned his art from a Jewish converso on the road to Santiago de Compostela. "Others thought Flamel was the creation of 17th-century editors and publishers desperate to produce modern printed editions of supposedly ancient alchemical treatises then circulating in manuscript for an avid reading public," Deborah Harkness put it succinctly.[1] The modern assertion that many references to him or his writings appear in alchemical texts of the 1500s, however, has not been linked to any particular source. The essence of his reputation is that he succeeded at the two magical goals of alchemy -- that he made the Philosopher's Stone which turns lead into gold, and that he and his wife Perenelle achieved immortality.
