Julius Sergius von Klever (31 January 1850, Tartu - 24 December 1924, Leningrad) was a Baltic German landscape painter.

[1] After completing his primary education, was enrolled at the Imperial Academy of Fine Arts where, at his father's insistence, he studied architecture.

After a short time, however, he began to take landscape painting classes; first with Sokrat Vorobiev, then Mikhail Clodt.

The resulting works were purchased by Pavel Tretyakov and the Imperial Family, including Tsar Alexander III.

Sometimes creating a picture a day, Klever began to quickly brush over the underpainting, made by his assistants.
