Marshal Cândido Rondon is considered one of the great national heroes of Brazil. As an engineer, he helped build a telegraph line across the rainforest. He built great roads, including the one from Rio to Cuiabá. He was a great friend to and advocate for indigenous tribes. He led an exploration fo the River of Doubt with Theodore Roosevelt. H was nominated for the Nobel Peace Prize for his humanitarian efforts during conflicts between Peru and Colombia. When he died in 1958, Brazil named a state Rondônia.
One of his exploits was to calculate the geographic center of South America, which he placed in the town of Cuiabá. A plaque was placed there in 1909, and an obelisk was built in 1975.
