Antonio Carlos Jobim was a very successful composer and arranger of music. He composed and performed "The Girl From Ipanema" many years ago. (Ipanema is one of the beachfront sections of Rio de Janeiro.)

If I remember correctly the airport at Sao Paulo (or the older airport in Rio) is named after Santos-Dumont, an early Brazilian pioneer of flight.

Don't think they've named an airport after one Joao Santos do Nascimento -- better known worldwide as soccer's (football's) Pele -- yet!
