Horace Bénédict De Saussure
Horace Bénédict de Saussure (17 February 1740 – 22 January 1799) was a Genevan geologist, meteorologist, physicist, mountaineer and Alpine explorer, often called the founder of alpinism and modern meteorology, and considered to be the first person to build a successful solar oven. Life and work Horace Bénédict de Saussure was born 17 February 1740, in Conches, near Geneva (''today in Switzerland but then an independent republic''), and died in Geneva 22 January 1799. Saussure's family were Genevan patricians. His father, Nicolas de Saussure, was an agriculturist and author. Because his mother was sickly, Saussure was brought up by his mother's sister and her husband the Genevan naturalist Charles Bonnet who sparked Horace-Bénédict's early interest in botany. After attending the "Collège" of his hometown, he completed his studies at the Geneva Academy in 1759 with a dissertation on heat (''Dissertatio physica de igne''). In 1760, he made the first of numerous trips ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanometer
A cyanometer (from ''cyan'' and '' -meter'') is an instrument for measuring " blueness", specifically the colour intensity of blue sky. It is attributed to Horace-Bénédict de Saussure and Alexander von Humboldt. It consists of squares of paper dyed in graduated shades of blue and arranged in a color circle or square that can be held up and compared to the color of the sky. History De Saussure, a Swiss physicist and mountain climber, is credited with inventing the cyanometer in 1789. De Saussure's cyanometer had 53 sections, numbered cards, ranging from white to varying shades of blue (dyed with Prussian blue) and then to black, arranged in a circle; he used the device to measure the color of the sky at Geneva, Chamonix, and Mont Blanc. De Saussure concluded, correctly, that the color of the sky was dependent on the amount of particles, water droplets and ice crystals, suspended in the atmosphere. Humboldt was also an eager user of the cyanometer on his voyages and explorati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The first magnetometer capable of measuring the absolute magnetic intensity at a point in space was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall effect, which is still widely used. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.

Chamonix
Chamonix-Mont-Blanc ( frp, Chamôni), more commonly known as Chamonix, is a commune in the Haute-Savoie department in the Auvergne-Rhône-Alpes region of southeastern France. It was the site of the first Winter Olympics in 1924. In 2019, it had a population of 8,640. Situated to the north of Mont Blanc, between the peaks of the Aiguilles Rouges and the notable Aiguille du Midi, Chamonix is one of the oldest ski resorts in France. The Chamonix commune is popular with skiers and mountain enthusiasts. Via the cable car lift to the Aiguille du Midi it is possible to access the off-piste (backcountry) ski run of the ''Vallée Blanche''. Name The name Campum munitum, meaning fortified plain or field, had been used as early as 1091. By 1283 the name had been abbreviated to a similar form to the modern Chamonis. Other forms through the ages include Chamouny in 1581, Chamony in 1652, Chamouni in 1786, and the particular spelling Chamonix from 1793. Status Chamonix is the fourth-largest ...

Jacques Balmat
Jacques Balmat (), called ''Balmat du Mont Blanc'' (1762–1834) was a mountaineer, a Savoyard mountain guide, born in the Chamonix valley in Savoy, at this time part of the Kingdom of Sardinia. Description A chamois hunter and collector of crystals, Balmat completed the first ascent of Mont Blanc with physician Michel-Gabriel Paccard on 8 August 1786. For this feat, King Victor Amadeus III gave him the honorary title ''du Mont Blanc''. Balmat and Paccard's ascent of Mont Blanc was a major accomplishment in the early history of mountaineering. C. Douglas Milner wrote "The ascent itself was magnificent; an amazing feat of endurance and sustained courage, carried through by these two men only, unroped and without ice axes, heavily burdened with scientific equipment and with long iron-pointed batons. The fortunate weather and a moon alone ensured their return alive." Eric Shipton wrote "Theirs was an astounding achievement of courage and determination, one of the greatest in t ...

Michel-Gabriel Paccard
Portrait of Michel Gabriel Paccard. Reproduced from an old portrait in the possession of M. J. P, Cachat, of Chamonix (his great grandson). From a photograph by Tairraz, of Chamonix Michel Gabriel Paccard (; 1757–1827) was a Savoyard doctor and alpinist, citizen of the Kingdom of Sardinia. Born in Chamonix, he studied medicine in Turin. Due to his passion for botany and minerals, he met Horace-Bénédict de Saussure, who initiated the race to be the first to ascend Mont Blanc. Gaston Rébuffat wrote "Like Saussure a devotee of the natural sciences, he has a dream: to carry a barometer to the summit and take a reading there. An excellent mountaineer, he has already made several attempts." Paccard had a first, unsuccessful, attempt in 1783 with Marc Theodore Bourrit. In 1784, he made several attempts with Jacques Balmat before they made the first ascent of Mont Blanc together on 8 August 1786. Balmat and Paccard's ascent of Mont Blanc was a major accomplishment in the early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Route The term "Mont Cenis" could derive from ''mont des cendres'' ("mountain of ashes"). According to tradition, following a forest fire, a great quantity of ashes accumulated on the ground, thus the name. The path of ashes was found during the building work of the route. The pass connects Val-Cenis in France in the northwest with Susa in Italy in the southeast. Thence the valley of the Dora Riparia is followed to Turin (103.8 km ...
