[1] His parents were Jean André Barrot (1753–1845), an advocate and deputy to the National Convention, and Théresa Virginie Borelli de Serre (1766–1858).

[1] He was appointed French Consul at Cartagena, Colombia, where he observed the slender-snouted or American crocodile (Crocodylus acutus).

[6] He wrote that in the Sandwich Islands (today's state of Hawaii), "we found the villages more European, and the people almost as vicious as those who have civilized them.

[11] His report and that of Captain Vaillant made the government more aware of the situation in Honolulu and the opposition by the king of Hawaii to missionary activity.

[9] In 1838 Barrot returned on leave from Manila, and in 1939 convinced the government and several leading trading houses of the great commercial potential of Southeast Asia.

[13] They left Singapore on 26 May 1840 on the Progrés, a Belgian ship, and reached Manila 45 days later after a slow passage due to contrary winds.

He collected much information about the trade in the region and strongly recommended that France establish a base there to compete with Singapore and Batavia.

[19] In 1845 Barrot was Consul General in Cairo and wrote to François Guizot, the Minister of Foreign Affairs, about the gum trade of Kordofan in the Sudan.

[21] In May 1846 Jules Itier and the members of a commercial delegation stayed with Barrot while returning from a visit to China after the end of the First Opium War.
