Scientist of the Day - Hippolyte Fizeau
Hippolyte Fizeau, a French physicist, was born Sep. 23, 1819. Fizeau was a master at designing experiments, most of them centered around light. He was exposed to photography almost from the moment that Louis Daguerre's discovery was announced by François Arago to the French Academy of Sciences in 1839, and Fizeau undertook his own investigations into how to reduce exposure time, which was around 30 minutes at the time, at which he was successful. In 1845, he and his friend Leon Foucault took a photograph of the Sun, the very first photograph ever taken of the Sun, which showed fields of sunspots quite clearly (the link is to the actual 1845 photograph).
Arago, the secretary of the French academy, who seems to have spent much of his life twisting people's arms, and who had asked Foucault and Fizeau to try to photograph the Sun, asked Fizeau to have a go at measuring the speed of light. Ole Rømer, long before (1676), had measured the speed of light indirectly by studying the moons of Jupiter and the variations in their eclipse times, but no one had ever measured the speed of light with an Earth-based experiment, After all, it takes light only one thousandth of a second (one millisecond) to go from Paris to Antwerp, so the

Hippolyte Armand Louis Fizeau
The French physicist Hippolyte Armand Louis Fizeau (1819-1896) is best remembered as the first to measure the speed of light without any recourse to astronomical observations.
Hippolyte Fizeau was born in Paris on Sept. 23, 1819, the son of a wealthy physician and professor at the Faculty of Medicine in Paris. Young Fizeau received his secondary education at the Collège Stanislas and first wanted to pursue a career in medicine, but because of poor health he had to discontinue regular attendance of classes. After a lengthy journey had restored him to health, he turned again to scientific studies. This time, however, he did not work for a degree, and instead of medicine he concentrated on physics.
It was mainly the experimental verification of theories that interested Fizeau, and he soon had a laboratory equipped for himself at home. His first achievement was an improvement on the daguerreotype process, a method discovered by Louis Daguerre in 1839 to produce photographic images. Fizeau substituted bromine for the iodine used by Daguerre. Through his work Fizeau developed a friendship with Léon Foucault, an enthusiast of the art of the daguerreotype. Together they collaborated to perfect the art for the use of celestial photography. The firs
