Alexandre Rodrigues Ferreira
Alexandre Rodrigues Ferreira (27 April 1756 – 23 April 1815) was a Portuguese naturalist born in Brazil. He undertook an extensive journey which crossed the interior of the Amazon Basin to Mato Grosso, between 1783 and 1792. During this journey, he described the agriculture, flora, fauna, and native inhabitants.
Born in Salvador, Bahia, the son of the merchant Manuel Rodrigues Ferreira, Ferreira began his studies at the Convent of Mercês, in Bahia, which gave him his first orders in 1768.
He then studied law and then natural philosophy and mathematics at the University of Coimbra, where he received his baccalaureate at age 22. He continued his studies at the institution, where he studied natural history, and obtained his doctorate in 1779.
He then worked at the Royal Museum of Ajuda. On 22 March 1780, he was admitted as a corresponding member of the Portuguese Royal Academy of Sciences.
At this time the colonial economy of Brazil was in a state of decadence, having exhausted the placer gold of Mato Grosso, Goiás, and, especially, Minas Gerais. For this reason, the queen Maria I of Portugal, desiring to know more about the central and north of the Brazilian colony, which at that point remained practically unexplored, in order to implement developmental measures, ordered Alexandre Rodrigues Ferreira, as a naturalist, to undertake a "philosophical voyage through the captaincies of Grão-Pará, Rio Negro, Mato Grosso e Cuiabá." The idea was to provide an impetus for economic exploration and enable conquest of disputed territory.
In 1783 the naturalist left his post at the Museum of Ajuda, and, in September, left for Brazil to describe, collect, prepare and remit to the Royal Museum of Lisbon samples of tools used by the local population, as well as local minerals, plants, and animals. He was also to write political and philosophical commentaries about what he saw in the places he passed through. This pragmatism was what separated this voyage from other, more scientific, voyages led by other naturalists who explored America.
With uncertain resources, he counted on two draftsmen or sketchers (riscadores), José Codina, about whom little is known, and José Joaquim Freire, who had an important position in the drawing house of the Museum of Ajuda and frequented the design halls of the Foundry of the Royal Army Arsenal. He was also served by a botanical gardener, Agostinho do Cabo. The voyage was undertaken under auspices of the Academy of Sciences in Lisbon, the Ministry of Business and Ultramarine Dominions, and was planned by the Italian naturalist Domenico Vandelli. It was originally planned to include four naturalists, but due to financial cuts, Ferreira was the only one, and on his shoulders lay the responsibilities of collecting species, classifying and preparing specimens for the return journey to Lisbon, and preparing studies about the agriculture and maps of the area.
In October 1783, he arrived in Belém do Pará on the Águia e Coração de Jesus ("Eagle and Heart of Jesus"). The following nine years were dedicated to crossing the central-north of Brazil, from the island of Marajó, Cametá, Baião, Pederneiras and Alcobaça.
