Jensen was the son of a bureaucrat. He studied medicine, history, and philosophy at the universities of Breslau and Munich. His lyric poetry is imbued with an elegiac mood (the collection Verses, 1869). Jensen is the author of realistic novels and short stories based on contemporary themes, such as Dark Erika (1868) and From an Old Family (1884). His most interesting novels are Around the Imperial Throne (1878) and Lost Worlds (1882). Jensen’s later works contain elements of fantasy (the novel Gradiva, 1903; Russian translation, 1912).
