Charles-François Daubigny
From 1854 to 1860, he travelled around Europe and worked prolifically. In Rome, he was acquainted with Alexander Ivanov, who convinced Bogolyubov to focus more on drawing. In Düsseldorf, Bogolyubov took classes from the painter Andreas Achenbach. In Paris, he admired the artists of the Barbizon School. French painters Camille Corot and Charles-François Daubigny were good friends and collaborators with Bogolyubov. He also painted the frescoes in the Alexander Nevsky Cathedral.
