Águas de São Pedro–São Paulo 1941 chess tournament
The Águas de São Pedro International Tournament () was a chess tournament held from 2 to 26 July 1941 in Águas de São Pedro and São Paulo. The event, the first international chess tournament of Brazil, was organized by the São Paulo Chess Club and sponsored by Antonio and Octavio Moura Andrade, being the latter founder of Águas de São Pedro and owner of the "Grande Hotel".
Água de Pau
There are various theories as to the origin of the villa's name, "Água de Pau", which literally means "water of wood" (which can be interpreted as "waters where wood exist"). The most recognized story pertains to early settlers whom, upon arriving in the vicinity of the coast, noticed a large ravine emptying into the ocean from a swamp. Another story defended locally is that the name derived from the corruption of the phrase "Água do Paul" ("paul" possibly being a term for swamp or bog), which itself referred to the "Ribeira do Paul", an old ravine that existed in the area behind the older parochial church of Nossa Senhora dos Anjos. The "Paul" has long since disappeared, and the area behind the church has been cultivated over the decades. Nossa Senhora dos Anjos dos Céus was founded, as was the custom, in the center of the faith community and it is likely that this area was an initial settlement for the community.
