Which Geneva journal published Menabrea's French transcript in 1842?

The Geneva journal that published Luigi Federico Menabrea’s French transcript in 1842 was Bibliothèque universelle de Genève. Menabrea’s paper presented Charles Babbage’s ideas about the Analytical Engine to a French-speaking audience.

Menabrea encountered Babbage during Babbage’s 1840 visit to Turin, where Babbage lectured on his proposed machine. Menabrea later turned those lectures into a French description, titled “Notions sur la machine analytique de M. Charles Babbage,” which appeared in the Geneva publication.

The paper became historically important because Ada Lovelace translated it into English and expanded it with her own notes. Her version was published in 1843 in Taylor’s Scientific Memoirs and included Note G, a detailed procedure for calculating Bernoulli numbers.

A common mix-up is to associate the paper with later scientific journals such as Comptes rendus or with general nineteenth-century physics periodicals such as Philosophical Magazine and Annalen der Physik. Those are plausible-sounding titles, but Bibliothèque universelle de Genève is the specific publication named in the historical record.
