Wikipedia:
José Bonifácio de Andrada e Silva, (13 June 1763 – 6 April 1838); was a Brazilian statesman, naturalist, mineralist, professor and poet, born in Santos, São Paulo, then part of the Portuguese Empire. He was one of the most important mentors of Brazilian independence, and his actions were decisive for the success of Emperor Pedro I. He supported public education, was an abolitionist and suggested that a new national capital be created in Brazil's underdeveloped interior (effected over a century later as Brasília). His career as naturalist was marked by the discovery of four new minerals.

Career in Europe
José Bonifácio spent part of his life in Europe. In his travels around Europe he studied chemistry and mineralogy with other scientists. He collected data, carried out scientific experiments and discovered four new minerals and eight previously unknown species. The mineral andradite is named for him. Among his other discoveries was petalite, a lithium-containing material, first discovered by Andrade toward the end of the 18th century on a trip to Sweden; it was in this mineral that Swedish chemists first discovered lithium. He also was the first to discover another important lithium-containing mineral, spodumene, from the same source, the island of Utö in the Stockholm Archipelago of Sweden.
