Jules Richard (photographer)
Jules Richard (19 December 1848 - 18 June 1930) was a French photographer, businessman and instrument maker. Trained in part by his father, an instrument maker, Richard took over the family's business on his father's death. Richard was the inventor and manufacturer of the Verascope and Glyphoscope stereographic cameras, and also the Taxiphote stereographic viewer. Early career Richard's father Félix Richard was an instrument maker in Paris; his uncle was the electrical instrument maker Paul-Gustave Froment. After training in the his father's workshop, he worked outside the family company in the 1870s, manufacturing telegraphy equipment. Following his father's death in 1876, he returned to the family business in 1877, working in partnership with his younger brother Max starting in 1882. During the 1880s they built a reputation for manufacturing scientific barometers, and other environmental recording devices such as anemometers, pyrometers, aneroid barographs and dynamometers. ...

Paul-Gustave Froment
Paul-Gustave Froment (born March 3, 1815 in Paris, died 1865) was a French mechanic, instrument maker and inventor. Life He was born in Paris and was educated at the Collège Sainte-Barbe and the Lycée Louis-le-Grand. Having demonstrated from childhood talent for technology, his father decided to let him study at the Ecole Polytechnique in Paris. He later moved to Britain to continue his studies in Manchester. He was also one of the earliest photographers, working with the Direct Positive Process. On his return to France, his intention was to build steam engines but he was prevented from doing so by lack of funds. Instead, he opened a Paris workshop in 1844 where, among other things, he worked on a telegraph with written and keyboard signals, improved Gaetan Bonelli's electric loom, and helped William Hughes improve his early typewriter. He also worked on the gyroscope with Léon Foucault, for whom he also made the pendulum for his famous demonstration in 1851. In 1854 h ...

Anemometer
In meteorology, an anemometer () is a device that measures wind speed and direction. It is a common instrument used in weather stations. The earliest known description of an anemometer was by Italian architect and author Leon Battista Alberti (1404–1472) in 1450. History The anemometer has changed little since its development in the 15th century. Alberti is said to have invented it around 1450. In the ensuing centuries numerous others, including Robert Hooke (1635–1703), developed their own versions, with some mistakenly credited as its inventor. In 1846, John Thomas Romney Robinson (1792–1882) improved the design by using four hemispherical cups and mechanical wheels. In 1926, Canadian meteorologist John Patterson (1872–1956) developed a three-cup anemometer, which was improved by Brevoort and Joiner in 1935. In 1991, Derek Weston added the ability to measure wind direction. In 1994, Andreas Pflitsch developed the sonic anemometer. Velocity anemometers Cup anemomet ...

Pyrometer
A pyrometer is a type of remote-sensing thermometer used to measure the temperature of distant objects. Various forms of pyrometers have historically existed. In the modern usage, it is a device that from a distance determines the temperature of a surface from the amount of the thermal radiation it emits, a process known as pyrometry and sometimes radiometry. The word pyrometer comes from the Greek word for fire, "πῦρ" (''pyr''), and ''meter'', meaning to measure. The word pyrometer was originally coined to denote a device capable of measuring the temperature of an object by its incandescence, visible light emitted by a body which is at least red-hot. Modern pyrometers or infrared thermometers also measure the temperature of cooler objects, down to room temperature, by detecting their infrared radiation flux. Principle It is based on the principle that the intensity of light received by the observer depends upon distance of observer from source and temperature of dis ...

Barograph
A barograph is a barometer that records the barometric pressure over time in graphical form. This instrument is also used to make a continuous recording of atmospheric pressure. The pressure-sensitive element, a partially evacuated metal cylinder, is linked to a pen arm in such a way that the vertical displacement of the pen is proportional to the changes in the atmospheric pressure. Development Alexander Cumming, a watchmaker and mechanic, has a claim to having made the first effective recording barograph in the 1760s using an aneroid cell.Gloria Clifton (2004)"Cumming, Alexander (1731/2–1814)", ''Oxford Dictionary of National Biography'', Oxford University Press. (Subscription or UK public library membership required) Cumming created a series of barometrical clocks, including one for King George III. However, this type of design fell out of favour. Since the amount of movement that can be generated by a single aneroid is minuscule, up to seven aneroids (so called Vidie-cans ...

Stereographic
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye move ...

History Of Science Museum, Oxford
The History of Science Museum in Broad Street, Oxford, England, holds a leading collection of scientific instruments from Middle Ages to the 19th century. The museum building is also known as the Old Ashmolean Building to distinguish it from the newer Ashmolean Museum building completed in 1894. The museum was built in 1683, and it is the world's oldest surviving purpose-built museum. History Built in 1683 to house Elias Ashmole's collection, the building was the world's first purpose-built museum building and was also open to the public. The original concept of the museum was to institutionalize the new learning about nature that appeared in the 17th century and experiments concerning natural philosophy were undertaken in a chemical laboratory in the basement, while lectures and demonstration took place in the School of Natural History, on the middle floor. Ashmole's collection was expanded to include a broad range of activities associated with the history of natural knowledge ...

1848 Births
1848 is historically famous for the wave of revolutions, a series of widespread struggles for more liberal governments, which broke out from Brazil to Hungary; although most failed in their immediate aims, they significantly altered the political and philosophical landscape and had major ramifications throughout the rest of the century.
