[1] Laurent could boast of the title "Fotógrafo de Su Majestad la Reina" (Her Majesty The Queen's Photographer) from 1861 to 1868.

[3] In 1874, he was commissioned by Baron Émile d’Erlanger to take photographs of Francisco de Goya's Black Paintings at the Quinta del Sordo.

[4] The photographs were later used as a guide by the artist, Salvador Martínez Cubells, to remove the paintings and restore them for public display.

When he was called to serve in the war in 1915, the collection was purchased by Joana Roig Villalonga, a Mallorcan, who continued to issue images under the name Casa Laurent until the archive was bought again, this time by another photographer, Joaquín Ruiz Vernacci [es], in 1930.

The National Gallery of Art, Washington, D.C. houses a collection of nearly 700 albumen prints made from Jean Laurent's photographs, many of which have been digitized.
