Charles Dillon Perrine (July 28, 1867 – June 21, 1951) was an American astronomer living in Argentina. He won the Lalande Prize in 1897. [1]

Born in Steubenville, Ohio, a son of Peter and Elizabeth McCauley Perrine, [2] and a descendant of Daniel Perrin, "The Huguenot", he worked at Lick Observatory in California from 1893 to 1909 and then was director of the Argentine National Observatory (today, Observatorio Astronómico de Córdoba) [3] in Argentina from 1909 until 1936.

Between 1900 and 1908, Perrine accompanied four eclipse expeditions and was in charge of the one sent from Lick Observatory to Sumatra in 1901. Also in 1901, he and George Ritchey observed the apparent superluminal motion in the nebulosity surrounding Nova Persei 1901. [2]

He discovered two moons of Jupiter, today known as Himalia (on December 3, 1904) and Elara (in 1905). They were simply designated "Jupiter VI" and "Jupiter VII" and were not given their present names until 1975.

Perrine co-discovered the lost periodic comet 18D/Perrine-Mrkos and several other comets. Antonín Mrkos later named the asteroid 6779 Perrine after him. The lunar crater Perrine is also named after him.

He promoted the study of astrophysics in Argentina and pushed for the construction of a large telescope (the Bosque Alegre telescope), which however was not completed until 1942 (he had retired in 1936). He remained in Argentina after retirement and died there, in Villa General Mitre (which has since been renamed to its original name of Villa del Totoral). He is buried in the Cementerio de Disidentes in the city of Córdoba.

James Lick telescope Telescope in California, United States

The James Lick Telescope is a refracting telescope built in 1888. It has a lens 36 inches (91 cm) in diameter- a major achievement in its day. The instrument remains in operation and public viewing is allowed on a limited basis. Also called the "Great Lick Refractor" or simply "Lick Refractor", it was the largest refracting telescope in the world until 1897 and now ranks third, after the 40-inch unit at the Yerkes Observatory and the Swedish 1-m Solar Telescope. The telescope is located at the University of California's Lick Observatory atop Mount Hamilton at an elevation of 4,209 feet (1,283 m) above sea level. The instrument is housed inside a dome that is powered by hydraulic systems that raise and lower the floor, rotate the dome and drive the clock mechanism to track the Earth's rotation. The original hydraulic arrangement still operates today, with the exception that the original wind-powered pumps that once filled the reservoirs have been replaced with electric pumps. James Lick is entombed below the floor of the observing room of the telescope.

The Great Comet of 1901, sometimes known as Comet Viscara, formally designated C/1901 G1, was a comet which became bright in the spring of 1901. Visible exclusively from the southern hemisphere, it was discovered on the morning of April 12, 1901 as a naked-eye object of second magnitude with a short tail. On the day of perihelion passage, the comet's head was reported as deep yellowish in color, trailing a 10-degree tail. It was last seen by the naked eye on May 23.
