Charles Dillon Perrine (July 28, 1867 – June 21, 1951) was an astronomer at the Lick Observatory in California (1893-1909) who moved to Cordoba, Argentina to accept the position of Director of the Argentine National Observatory (1909-1936). The Cordoba Observatory under Perrine's direction made the first astronomical attempts to prove Einstein's theory of relativity by observation of the deflection of starlight near the Sun during the solar eclipse of Oct. 10, 1912 in Cristina, Brazil, and the solar eclipse of August 21, 1914 at Feodosia, Crimea, Russian Empire. Rain in 1912 and clouds in 1914 obscured the eclipses.[1]

In 1897 he was awarded the Lalande Prize and gold medal by the Paris Academy of Sciences given each year ″to the person who makes the most outstanding observation ... to further the progress of Astronomy, in France or elsewhere.″[2]. He served as President of the Astronomical Society of the Pacific in 1902[3][4], was elected an Associate of the Royal Astronomical Society in 1904[5], and was awarded the gold medal of the Mexican Astronomical Society in 1905. In the same year he received the degree of Doctor of Sciences (honorary) from Santa Clara College (today Santa Clara University.[6]

Born in Steubenville, Ohio, the son of Peter and Elizabeth (McCauley) Perrine[7][8], he was a descendant of Daniel Perrin, "The Huguenot", and Maria Thorel. Theirs was the first recorded European marriage in Elizabethtowne, New Jersey (Feb. 18, 1666).[9] Following high school graduation in 1884[10], he moved to Alameda, California in about 1886 and worked as a bookkeeper at Armour & Co. in San Francisco.

Interested in photography and astronomy from an early age[11], and unable to afford a college education, "he nevertheless looked forward to engaging in astronomical work".[12] Perrine responded to a general invitation to amateurs from E. S. Holden, the Director of the newly established Lick Observatory[13] (1888), to observe the total solar eclipse of Jan. 1, 1889 in Northern California. His report and photographs[14] caught the attention of the Director who hired him as Secretary in 1893[15]. Holden agreed to Perrine's "fixed purpose of devoting his spare time to the study of astronomical and related subjects, by way of preparation for later observatory duties".[16] As his experience, skills, and discoveries grew he was promoted to Secretary and Assistant Astronomer (1895)[17], Assistant Astronomer (1902)[18], and Astronomer (1905)[19].

From 1895-1902 Perrine discovered eight unexpected and four periodic comets including the co-discovery of the lost periodic comet 18D/Perrine-Mrkos in 1896 (see list below).[20][21] Antonín Mrkos later named the asteroid 6779 Perrine after him. The lunar crater Perrine is also named after him.

He discovered the sixth and seventh moons of Jupiter, today known as Himalia (on December 3, 1904) and Elara (on Feb 21, 1905). At the time they were simply designated "Jupiter VI" and "Jupiter VII" and were given their present names in 1975.[22]

Perrine accompanied four solar eclipse expeditions of the Lick Observatory: 1900 (Georgia, USA), 1901 (Sumatra), 1905 (Spain), and 1908 (Flint Island)[23], and was in charge of the one sent to Sumatra[24]. Also in 1901, he and George Ritchey observed the apparent superluminal motion in the nebulosity surrounding Nova Persei 1901.[8]

In 1909 he resigned from Lick Observatory to accept the position of Director of the Argentine National Observatory (today, Observatorio Astronómico de Córdoba)[25][26] at Cordoba, Argentina from 1909 until 1936.

The Argentine National Observatory led by Perrine made the first attempt to test Albert Einstein's Theory of Relativity by observing the deflection of star light near the Sun at a total solar eclipse.[27][28][29][30][31] Perrine wrote, "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."[32] 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 deflection near the Sun),...".[33] Dr. Erwin Finlay-Freundlich, a German astronomer and mathematician, took up Einstein's challenge and contacted Perrine in 1911 and 1912 to ask if he would undertake a test of light deflection 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.[34] William Wallace Campbell, the Director of the Lick Observatory, also encouraged Perrine to pursue the test and loaned him Lick's eclipse camera lenses.[35] The Argentine National Observatory built the telescopes and established the observation site at Cristina, Brazil. Unfortunately, steady rain made visibility and therefore the test impossible. As Perrine put it, "We suffered a total eclipse instead of observing one".[36] While evidence of light deflection was elusive in 1912, the expedition produced valuable instruments and experience which put the Observatory in a better position to test light deflection at the next solar eclipse in 1914. Perrine soon began to plan for this next opportunity in the Russian Empire. Three observatories would organize expeditions and include light deflection in their programs for 1914; the Argentine National Observatory (Perrine), the Lick Observatory (Campbell), and the Berlin-Babelsberg Observatory (Freundlich).[37]

Perrine pioneered the study of astrophysics in Argentina and promoted the construction of the 60-inch/1.54 m reflecting telescope at Bosque Alegre which was completed in 1942 after his retirement in 1936.[38] It would remain the largest telescope in South America until 1981 when Brazil built a 63-inch reflector.[39][circular reference] After retirement he lived in Cordoba then in Villa General Mitre (originally and again Villa del Totoral) where he died. He is buried in the Cemetery del Salvador (Cementerio del Salvador) formerly called the Cementerio de Disidentes (cemetery of dissidents/non-catholics), in the city of Córdoba.[40]
