Charles Dillon Perrine (July 28, 1867 – June 21, 1951) was an American astronomer living in Argentina. He won the Lalande Prize in 1897.[1], and in 1902 was President of the Astronomical Society of the Pacific.[2]

Born in Steubenville, Ohio, a son of Peter and Elizabeth McCauley Perrine,[3][4] and a descendant of Daniel Perrin, "The Huguenot".[5] He worked at Lick Observatory in California from 1893 to 1909 in the capacity of Secretary (1893)[6], Secretary and Assistant Astronomer (1895)[7], Assistant Astronomer (1902)[8], and Astronomer (1905)[9]. In 1909 he resigned from Lick Observatory to accept the position of Director of the Argentine National Observatory (today, Observatorio Astronómico de Córdoba)[10][11] 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.[4]

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.

As director of the Argentine National Observatory in Cordoba, Perrine designed and led the first astronomical attempt to test Einstein's Theory of Relativity by observing the deflection of star light near the Sun at a total solar eclipse.[12][13][14] In Perrine's own words, "The Cordoba Observatory made the first definite attempt to secure observations at an eclipse (that of 1912) for the relativity problem and that was done at the instigation of Dr. Freundlich."[15] Albert Einstein, in 1905, had proposed his Theory of Special Relativity which predicted that gravity bent light. In 1911 Einstein wrote, "It would be urgently wished that astronomers take up the question here raised (gravitational light-bending),...".[16] Dr. Freundlich, a German astronomer, took up Einstein's challenge and contacted Perrine in 1911 and 1912 to ask if he would undertake a test of light-bending near the Sun. Perrine agreed to add the test to his planned expedition to Cristina, Brazil to observe the total solar eclipse of Oct. 10, 1912. William Wallace Campbell, the Director of the Lick Observatory, also encouraged Perrine to pursue the test and loaned him telescopic/camera lenses for the purpose. Perrine designed and had built the necessary telescopes/cameras at the Argentine Observatory which he transported to and set up at the observation site. Unfortunately, steady rain made visibility of the brief eclipse and the test impossible. As Perrine put it, "We suffered a total eclipse instead of observing one".[17]

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.
