Who are some famous Mexican/Brazilian mathematicians?

Question

I have a project I need to do for school (make a 15 page children's describing a mathematician that has the same nationality as me).

I am Mexican and Brazilian, so I need to find at least one mathematician that is either Mexican or Brazilian (or both, doesn't really matter... just has to be at least one of the two) that has made quite a few contributions that would be easy to explain in a children's book.

If the works aren't easy to explain in a children's book, but you still want to provide the mathematician's name, please do so anyways, and suggest a way that I might explain their works to a child.

So when you respond, please include the name, nationality [mexican/brazilian], and his/her contributions.

Thank you.

Víctor Neumann-Lara also Víctor Neumann (1933-2004) was a Mexican mathematician

Full Professor at Institute of Mathematics, UNAM, he directed over 15 theses and taught both in the Institute and in the Faculty of Sciences. Below is a selection of his multiple publications, which earned him over 120 citations from renown mathematicians in the area of graph theory.

In 1982 he introduced the notion of dichromatic number of a digraph, which will eventually be used in kernel theory and tournament theory.
