Josiah Wedgewood (Ceramics)
Birthday: 1730, Burslem, Staffordshire, England
Josiah Wedgewood, born into a family of potters, sought always to improve the quality of his pottery. He was friendly with several noted scientists (Boulton, Keir, Priestly, Withering) and their advice about chemistry and mineralogy helped him devise new types of pottery such as green glaze, creamware, and jaspar. Wedgewood published papers on mineralogy and pyrometry.

Claude Bernard (Medicine, Biology, Physiology)
Birthday: 1813, Saint-Juilien, France
Claude Bernard qualified at Paris as a physician and then devoted himself to the experimental investigation of physiology. He showed that the stomach was not the entire seat of digestion, that certain nerves control the dilation of blood vessels, that red blood cells carry oxygen to body cells, that glycogen is stored in the liver, and showed how carbon monoxide acts as a poison.
"The true worth of an experimenter consists in his pursuing not only what he seeks in his experiment, but also what he did not seek."
