Hermann Prell (29 April 1854 – 18 May 1922) was a German history painter, sculptor and professor at the Dresden Academy of Fine Arts.
He was born at Leipzig and studied under Theodor Grosse in Dresden and Karl Gussow in Berlin, then went to Italy to study fresco painting with Hans von Marées, in which style he produced the bulk of his works, despite Marées skepticism regarding his talent.
In 1892, he was appointed a Professor at the Dresden Academy of Fine Arts and remained there until his retirement in 1914.
In later life, he executed sculptures and collaborated on several projects with Otto Lessing, Christian Behrens and Alfred Messel.
His brother was the landscape painter, Walter Prell [de] and his son, Heinrich was a zoologist.
