Thanks for mentioning this. Though I think it is well known that Arabic and Indian societies were ahead of Europe with regards to mathematics for a long time, I have never thought about the lack of famous mathematicians outside of Europe. That being said, any serious mathematician would say that being a great mathematician is just as much as being at the right place at the right time as a being a genius. It is sad that these names are, if not lost to history, at least not well known, but praising any name of a discipline that builds on previous works in the way mathematics does is a little wrong in the first place. Even the dickhead Newton admitted as much with the “shoulders of giants” comment with regards to himself.
