Diogo Ribeiro

Diogo Ribeiro (d. 16 August 1533) was a Portuguese cartographer and explorer who worked most of his life in Spain, where he was known as Diego Ribero.

[3] By 1516, Diogo Ribeiro and several other Portuguese navigators and cartographers, conflicting with King Manuel I of Portugal, gathered in Seville to serve the newly crowned Charles V of Spain.

Among them were explorers and cartographers Diogo and Duarte Barbosa, Estêvão Gomes, João Serrão, Ferdinand Magellan and Jorge Reinel, cosmographers Francisco and Ruy Faleiro and the Flemish merchant Christopher de Haro.

Ribeiro started working for Charles I (and V of the Holy Roman Empire) in 1518, as a cartographer at the Casa de Contratación in Seville.

On January 10, 1523, he was named Royal Cosmographer and "master in the art of creating maps, astrolabes, and other instruments".

It also shows, for the first time in cartography, the North American coast as a continuous one (probably influenced by Estêvão Gomes's explorations in 1524–1525).
