Jacqueline Lafontaine-Dosogne (23 November 1928, in Braine-l'Alleud - 21 May 1995, in Brussels) was a Belgian researcher, curator of the Royal Museums of Belgium, and a specialist in the Byzantine Empire and, more broadly, in the history of Christian art.

[1] She studied at the Free University of Brussels, where she earned a degree in art history and archaeology (1955), before pursuing a doctorate in philology and classical literature, which she obtained in 1961.

[1] She was an accomplished polyglot, which aided her in her research and travels, and spoke French, English, and Italian fluently, and had a very good understanding of German, Dutch, Modern Greek, and Russian, with some knowledge of Turkish, Bulgarian, Romanian, and Spanish.

[2][3][4] In the course of this research, she highlighted the connections between apocryphal literature on the childhood, such as the Protoevangelium of James and Byzantine hymnography, like the Akathist Hymn.

[2] The researcher joined the National Society of Antiquaries of France in 1978, on the recommendation of André Grabar and with the sponsorship of Louis Grodecki.
