Frédéric Sy
Frédéric Sy (1861-1917) was a French astronomer and a discoverer of minor planets. He worked at the Paris Observatory from 1879 to 1887, and as the assistant astronomer at the Algiers Observatory, North Africa, from 1887 to 1918. While working in Algiers he published extensively on the subjects of minor asteroids and comets, and was a colleague of astronomer François Gonnessiat. Sy was responsible for the discovery and naming of two asteroids, 858 El Djezaïr and 859 Bouzaréah. The names were drawn from locations near the discovering Algiers Observatory. He was awarded the Valz Prize ''(Prix Valz)'' in 1919 by the French Academy of Sciences. The asteroid 1714 Sy was named after him in 1951.

CRAAG - Bouzareah
The Algiers Observatory was built in the late 19th century in the Algiers suburb of Bouzaréah, Algeria, North Africa. It participated in the Astrographic Catalogue project, taking the zone between -2 and +4 degrees to expose 1,260 plates between the years 1891 and 1911. At the tail end of that time, the director of the installation was François Gonnessiat. It is now known as the Centre de Recherche en Astronomie Astrophysique et Géophysique (CRAAG), where it combines astronomy with work in astrophysics, and geophysical research, including the monitoring of earthquakes.
