Orville Adalbert Derby Geologist

Orville Adalbert Derby (Portuguese pronunciation: [ˈɔɾviɫ ɐdzawˈbɛɾts ˈdɛɾbi], Kellogsville, New York, July 23, 1851, — Rio de Janeiro, November 27, 1915) was an American geologist who worked in Brazil. Derby studied geology at the 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 a study travel to Brazil (the Morgan Expedition), and returning again with him in 1871, this time going to the Tapajós River in the Amazon. Just after his graduation, Derby accepted a 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 got his doctoral degree with a dissertation on the Carboniferous brachiopoda in the Amazon. When Hartt organized the first Geological Commission of the Empire of Brazil, Derby was nominated 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.

1. Cornell University Colleges/University

Cornell University ( /kɔrˈnɛl/ kor-NEL) is a private Ivy League research university located in Ithaca, New York, United States. It is a private land-grant university, receiving annual funding from the State of New York for certain educational missions. Founded in 1865 by Ezra Cornell and Andrew Dickson White, the university was intended to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's motto, a popular 1865 Ezra Cornell quotation: "I would found an institution where any person can find instruction in any study.
