The son of a Pisan merchant (and probably consul), posthumously known as Fibonacci (c. 1170 – c. 1250), there learned about mathematics (which he called "Modus Indorum") and Hindu-Arabic numerals. He introduced modern mathematics into medieval Europe. A mathematical-historical analysis of Fibonacci's context and proximity to Béjaïa, an important exporter of wax in his time, has suggested that it was actually the bee-keepers of Béjaïa and the knowledge of the bee ancestries that truly inspired the Fibonacci sequence rather than the rabbit reproduction model as presented in his famous book "Liber Abaci".
