Jacques Fabrice Herman Perk was an important Dutch poet of the late 19th century, who died young. His crown of sonnets Mathilde, published by Willem Kloos, was the first important announcement of a renewal in Dutch poetry brought about by artists that came to be known as the Tachtigers. Perk's lyrical poems about nature, especially his sonnets, were influenced by Percy Bysshe Shelley, and were of great importance to Dutch poetry.
