Rumpf was a genre, landscape and portrait painter, born in Frankfurt am Main. While studying in Paris he was influenced by Courbet, and subsequently often worked out of doors. He often portrayed children and rural life.

In 1858 he was one of the founders of the Kronberger Malerkolonie (Cronberg painting colony) located in Kronberg im Taunus, one of the earliest painting colonies in Germany. The members were influenced by Wilhelm Leibl, and through him the group was connected to the Barbizon school and Gustave Courbet. They emphasised "naturalism" and painting out of doors ("en pleine air").
