Frédéric Alexianu, known as F. Hugo d'Alesi, was a French painter, poster artist and illustrator of Austrian origin, born in Hermannstadt (Grand-Principality of Transylvania in the Austrian Empire) on February 10, 1849 and died in Paris on November 11, 1906.

He produced a large number of tourist posters for railroad companies at the end of the 19th century.

In addition to numerous posters for the Paris to Orleans, PLM and Western railways, Hugo d'Alesi designed posters for shipping companies and automobile manufacturers.

He also produced engravings of French cities, such as a panoramic view of the city and port of Bordeaux in 1889.

His posters Centenaire de la lithographie. Galerie Rapp (1895) and Chemin de fer de l'Est : Venise were reproduced in Les Maîtres de l'affiche, the magazine founded by Jules Chéret.

He also painted military compositions in oils.

Following Jules Ferry's Commission de décoration scolaire, he was approached to create school imagery, in particular “tableaux scolaires” (thematic maps), which were presented at the 1900 Universal Exhibition.

Hugo d'Alesi created the panoramic paintings for Le Maréorama, an attraction combining a large moving platform and two scrolling panoramic paintings. The Maréorama was presented at the 1900 Universal Exhibition in Paris.
