His most recognizable moniker is derived from his father’s, which meant “good-natured” or “simple”, and he was merely his father’s son.  During his extensive travels, he also picked up the label Bigollo, meaning “wanderer”.

His most famous contribution to mathematics was originally proposed by an Indian mathematician named Acharya Hemachandra, and was presented to the Western world as an example of place values in counting, which made the Indo-Arabic system superior to Roman numerals.

This work was published as Liber Abaci or The Book of Calculations in 1202.
