Henri Joseph Anastase Perrotin (December 19, 1845 – February 29, 1904) was a French astronomer. Some sources give his middle name as Athanase.
In his early career, he and Guillaume Bigourdan were assistants of Félix Tisserand at Toulouse Observatory. Later, he was the directory of the Nice Observatory in Nice, France from 1884 until his death. He made observations of Mars and attempted to determine the rotation period of Venus. He also calculated perturbations in the orbit of 4 Vesta.
In the literature, he is sometimes referred to as Henri Perrotin and sometimes as Joseph Perrotin (this is indeed one and the same person). His asteroid discoveries are credited by the Minor Planet Center to "J. Perrotin".
Perrotin crater on Mars has been named in his honor, as has asteroid 1515 Perrotin.

Famous quotes containing the word henri:
“Since I am a man, my heart is three or four times less sensitive, because I have three or four times as much power of reason and experience of the world—a thing which you women call hard-heartedness. As a man, I can take refuge in having mistresses. The more of them I have, and the greater the scandal, the more I acquire reputation and brilliance in society.”
—Stendhal [Marie Henri Beyle] (1783–1842)
