Little girl looking Dear readers, Catholic Online was de-platformed by Shopify for our pro-life beliefs. They shut down our Catholic Online, Catholic Online School, Prayer Candles, and Catholic Online Learning Resources—essential faith tools serving over 1.4 million students and millions of families worldwide. Our founders, now in their 70's, just gave their entire life savings to protect this mission. But fewer than 2% of readers donate. If everyone gave just $5, the cost of a coffee, we could rebuild stronger and keep Catholic education free for all. Stand with us in faith. Thank you. Help Now >

Antoine d'Abbadie

Astronomer, geodetist, genographer, physician, numismatist, philologian, born 1810; died March 20, 1897.

While still a young man, he conceived the project of exploring Africa. Having prepared himself by six years' study, he spent ten years exploring Ethiopia, and achieved scientific results of the greatest value. D'Abbadie was a fervent Catholic, and during his explorations in Ethiopia made every effort to plant there the Catholic Faith. It was at his suggestion and that of his brother Arnauld, companion and colabourer of Antoine, that Gregory XVI sent missionaries to carry on the work. He published in the "Revue des Questions Scientifiques," the organ of the society, a work on the abolition of African slavery. He gave his estate, called Abbadia, in southern France, to the Academy of Sciences of Paris, to carry on research. His will provided, furthermore, for the establishment of an observatory at Abbadia, where a catalogue of 500,000 stars must be made, the work to be confided to religious and to be completed before 1950.

His principal writings are: "Catalogue raisonné de manuscrits éthiopiens" (Paris, 1859); "Résumé Géodésique des positions déterminées en Ethiopie: (Paris, 1859); "Géodésie d'Ethiopie ou Triangulation d'une patrie de la haute Ethiopie: (4 vols., Paris, 1860-73);"Observations relatives à la physique du globe, faites au Brésil et en Ethiopie" (Paris, 1873); "Dictionnaire de la langue Amariñña."

Arnauld Michel d'Abbadie

Geographer, younger brother of preceding, b. in Dublin, Ireland, 1815; d. 8 November, 1893. In 1837 he accompanied his brother's expedition to Abyssinia, where he soon acquired considerable influence, and never failed to employ it in the interest of the Catholic missions. His most important work is "Douze ans dans la haute Ethiopie" (Paris, 1868).
