Ubiratan D’Ambrosio has been considered as the father of ethnomathematics; above all, in his conception of the term Ethnomathematics.

Both were interested in the History and Epistemology of Mathematics, from the perspective of ethnomathematics. Here, I will try to highlight some of their ideas and discuss implications.
