Giovanni Virginio Schiaparelli

HFRSE (/ˌskæpəˈrɛli, ˌʃæp-/ SKAP-ə-REL-ee, SHAP-,[2][3] US also /skiˌɑːp-/ skee-AHP-,[3][4] Italian: [dʒoˈvanni virˈdʒiːnjo skjapaˈrɛlli]; 14 March 1835 – 4 July 1910) was an Italian astronomer and science historian

Biography

He studied at the

St Petersburg, and then worked for over forty years at Brera Observatory in Milan. He was also a senator of the Kingdom of Italy, a member of the Accademia dei Lincei, the Accademia delle Scienze di Torino and the Regio Istituto Lombardo, and is particularly known for his studies of Mars

Mars

Main article: Martian canals
Schiaparelli's 1877 surface map of Mars

Among Schiaparelli's contributions are his telescopic observations of Mars. In his initial observations, he named the "seas" and "continents" of Mars. During the planet's "great opposition" of 1877, he observed a dense network of linear structures on the surface of Mars, which he called canali in Italian, meaning "channels", but the term was mistranslated into English as "canals".[5]

While the term "canals" indicates an artificial construction, the term "channels"

Martians, intelligent life living on Mars. Among the most fervent supporters of the artificial-canal hypothesis was the American astronomer Percival Lowell, who spent much of his life trying to prove the existence of intelligent life on the red planet.[5] After Lowell's death in 1916, astronomers developed a consensus against the canal hypothesis, but the popular concept of Martian canals excavated by intelligent Martians remained in the public mind for the first half of the 20th century and inspired a corpus of works of classic science fiction
.

Later, with notable thanks to the observations of the Italian astronomer

optical illusions. The last popular speculations about canals were finally put to rest during the spaceflight era beginning in the 1960s, when visiting spacecraft such as Mariner 4
photographed the surface with much higher resolution than Earth-based telescopes, confirming that there are no structures resembling "canals".

In his book Life on Mars, Schiaparelli wrote: "Rather than true channels in a form familiar to us, we must imagine depressions in the soil that are not very deep, extended in a straight direction for thousands of miles, over a width of 100, 200 kilometres and maybe more. I have already pointed out that, in the absence of rain on Mars, these channels are probably the main mechanism by which the water (and with it organic life) can spread on the dry surface of the planet."

Astronomy and history of science

An observer of objects in the

rotation periods.[8] In 1965, it was shown that his and most other subsequent measurements of Mercury's period were incorrect.[9]

Schiaparelli was a scholar of the history of classical astronomy. He was the first to realize that the concentric spheres of Eudoxus of Cnidus and Callippus, unlike those used by many astronomers of later times, were not to be taken as material objects, but only as part of an algorithm similar to the modern Fourier series.[citation needed]

He was elected to the American Philosophical Society in 1901.[10]

His niece, Elsa Schiaparelli, became a noted designer or maker of haute couture.[14]
