John James Audubon
John James Audubon (born Jean Rabin; April 26, 1785 – January 27, 1851) was an American ornithologist, naturalist, and painter. He was notable for his extensive studies documenting all types of American birds and for his detailed illustrations that depicted the birds in their natural habitats. His major work, a color-plate book entitled The Birds of America (1827–1839), is considered one of the finest ornithological works ever completed. Audubon identified 25 new species.
Anselmus Boëtius de Boodt
Anselmus de Boodt or Anselmus Boëtius de Boodt (Bruges, 1550 - Bruges, 21 June 1632) was a Flemish humanist, mineralogist, physician and naturalist. Along with the German known as Georgius Agricola, de Boodt was responsible for establishing modern mineralogy. De Boodt was an avid mineral collector who travelled widely to various mining regions in Germany, Bohemia and Silesia to collect samples. His definitive work on the subject was the Gemmarum et Lapidum Historia (1609).
