John James Audubon (Jean-Jacques Audubon) was a French-American ornithologist, naturalist, and painter. He was notable for his expansive studies to document 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 North America
(1827–1839), is considered one of the finest ornithological works ever completed. Audubon identified 25 new species and a number of new sub-species.

Karl Drais was a German inventor and invented the Laufmaschine ("running machine"), also later called the velocipede, draisine
(English) or "draisienne" (French), also nicknamed the dandy horse. This incorporated the two-wheeler principle that is basic to the bicycle and motorcycle and was the beginning of mechanized personal transport. Drais also invented the earliest typewriter with a keyboard in 1821, later developed into an early stenograph machine, and a wood-saving cooker including the earliest hay chest.
