Joanny-Philippe Lagrula (1870–1941) was a Frenchastronomer.[1] He was sometimes referred to asPhilippe Lagrula.
In 1901, he wrote his thesis[2] at theUniversity of Lyon. At the time, occultations of thePleiades by theMoon were important for measuring the correspondence of the Moon's actual position with that predicted by theory.
He worked at the Observatory ofLyon, France. On August 1, 1906, he became director of theQuito Astronomical Observatory for a few years. He then worked atNice Observatory until 1924, when he joined the staff ofAlgiers Observatory. He was director ofAlgiers Observatory from 1931 to 1938, replacingFrançois Gonnessiat who retired. His career path mirrored that of Gonnessiat, who had also worked at Lyon, and at the observatories inQuito and Algiers.
At Algiers, one of the staff members working with him wasJean-Louis Lagrula; this may have been his son[citation needed].
He discovered one asteroid. The asteroid1412 Lagrula is named after him.
