Actually, how can you prove that the earth is a rotating orb in an easy-to-see experiment and – of course – without spaceflight? By today, Foucault’s simple device is part of numerous natural science museums around the world. Ok, how does…

Fizeau, Foucault and Astronomical Photography

Fizeau, Foucault and Astronomical Photography

On April 2, 1845, Armand Hippolyte Louis Fizeau and Jean Bernard Léon Foucault manage to make the very first photography of the Sun. Thereby, they both initiate astronomical photography. From a previous blog post you may remember Léon Foucault’s Pendulum.[4] The instrument was used to proof Earth’s rotation in the 1850s and counts to one of Foucault’s biggest scientific achievements. But let’s start a little bit earlier. Leon Foucault was born on September…

Making Photography Really Operational – Louis Daguerre

Making Photography Really Operational – Louis Daguerre

Louis Daguerre (1787-1851) On August 19, 1839, French artist and physicist Louis Jacques Mandé Daguerre, after announcing his invention to the French Academy of Sciences, went public with his newly developed photographic process called Daguerrotype, the wold’s first practicable photographic process. Actually, Louis Daguerre did not invent photography, but, in 1829, he partnered with Nicéphore Niépce, an inventor who had produced the world’s first heliograph in 1822 and the first permanent camera…

Nicéphore Niépce and the World’s First Photograph

Nicéphore Niépce and the World’s First Photograph

On March 7, 1765, French inventor Nicéphore Niépce was born, who is best known as one of the inventors of photography and a pioneer in the field. He developed heliography, a technique used to produce the world‘s first known photograph in 1825. Niépce was born in Chalon-sur-Saône, Saône-et-Loire, where his father Claude Niépce was a wealthy lawyer and the king’s counsellor, which caused the family to flee the French Revolution. His older…
