Orville Adalbert Derby
American geologist and palaeontologist (1851–1915)
Orville Adalbert Derby (Portuguese pronunciation: [ˈɔʁviw ˈdɛʁbi]; July 23, 1851 in Kelloggsville, New York – November 27, 1915) was an American geologist who worked in Brazil.
Education
Derby studied geology at Cornell University, obtaining his degree in 1873. While a student, he was invited in 1870 by his professor Charles Frederick Hartt (1840–1878) to follow him in study travel to Brazil (the Morgan Expedition), and returning with him in 1871, this time going to the Tapajós River in the Amazon. Just after his graduation, Derby accepted the post of assistant professor at Cornell and briefly substituted for Hartt during another travel to Brazil in 1874. In June of the same year, Derby defended his doctoral thesis on the carboniferous brachiopoda in the Amazon.
Brazil
When Hartt organized the first Geological Commission of the Empire of Brazil, Derby was nominated as its assistant and returned to Brazil in December 1875. In 1877, with the end of the Commission, Derby decided to stay in Brazil and accepted a post at the National Museum of Rio de Janeiro. He became also a member and director of the Geographic and Geological Commission of São Paulo from 1886 to 1904. This commission later originated the Astronomical and Geophysical Institute of the University of São Paulo. Derby founded also the first Botanical Gardens in São Paulo ("Horto Botânico").

The first chronological checks are 1851, 1915, 1873 and 1870.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
