Who invented Hypo photography?
John Herschel
‘Hypo’ solutions became the means by which photographs were made permanent. On September 9, 1839 John Herschel took the first ever photo captured on glass plate. The photo shows the structure that supported his father’s 40-foot telescope in Slough.

What was Herschel’s contribution to photography?
Herschel made numerous important contributions to photography. He made improvements in photographic processes, particularly in inventing the cyanotype process, which became known as blueprints, and variations, such as the chrysotype.
What was William Herschel theory?
In 1785 he developed a cosmogony—a theory concerning the origin of the universe: the stars originally were scattered throughout infinite space, in which attractive forces gradually organized them into even more fragmented and tightly packed clusters.
When was Hypo invented?
An accomplished chemist, Herschel discovered the action of hyposulfite of soda on otherwise insoluble silver salts in 1819, which led to the use of “hypo” as a fixing agent in photography. In 1839, independently of William Henry Fox Talbot, Herschel also invented a photographic process using sensitized paper.

What did the Herschel experiment?
Herschel discovered the existence of infrared light by passing sunlight through a glass prism in an experiment similar to the one we describe here. As sunlight passed through the prism, it was dispersed into a rainbow of colors called a spectrum. A spectrum contains all the visible colors that make up sunlight.
What is the importance of the Herschel experiment?
Herschel’s experiment was important because it marked the first time that someone demonstrated that there were types of light that we cannot see with our eyes.

How did Herschel invent Cyanotypes?
In 1842, Herschel invented the cyanotype. The cyanotype process uses light-sensitive iron salts produced by brushing solutions of ferric ammonium citrate and potassium ferricyanide, also known as Prussian blue, onto paper, which is then dried in the dark.
Who discovered Mars?
Galileo Galilei
Galileo Galilei (1564 – 1642) observes Mars with a primitive telescope, becoming the first person to use it for astronomical purposes.
What telescope did William Herschel invent?
William Herschel’s 40-foot telescope, also known as the Great Forty-Foot telescope, was a reflecting telescope constructed between 1785 and 1789 at Observatory House in Slough, England. It used a 48-inch (120 cm) diameter primary mirror with a 40-foot-long (12 m) focal length (hence its name “Forty-Foot”).
