Source-derived summary

François Gonnessiat (May 22, 1856 (Nurieux-Volognat)–October 18, 1934) was a French astronomer, observer of comets and discoverer of two minor planets.

He worked at the Observatory of Lyon. In 1889 he won the Lalande Prize for astronomy from the French Academy of Sciences; 1901 became director of the Quito (Ecuador) Observatory for the purpose of making geodetic measurements. He became a well known and respected member of the academic scene of the city, where a street is named after him. From 1908 to 1931, he was director of the Algiers Observatory where one of his colleagues was Benjamin Jekhovsky. He was also director of the Quito Astronomical Observatory.

The asteroid 1177 Gonnessia was named in his memory (H 109).

Obituary

The obituary notice incorrectly states that he was director of the Algiers Observatory only until 1916, rather than 1931.

Editorial summary

This brief starts where responsible research should: with the source description of “François Gonnessiat” as french astronomer (1856–1934). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1856, 1934, 1889, 1901—that can be checked directly. The linked authority record independently contributes the date 1856-05-22. The account is most persuasive where François, Gonnessiat and French can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as french astronomer (1856–1934). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 7, 2026. The linked authority identifier is Q953726. VIAF identifies the subject as 37284656. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1856, 1934, 1889 and 1901.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
