(14 May 1824 - 6 October 1882) was a Danish marine artist, the brother of Anton Melbye and Fritz Melbye. He worked in London from 1853 to 1866 and, over the course of his career, painted seascapes, coastal and harbor scenes, sailing vessels and topographical subjects in many parts of Europe, especially in the Mediterranean region.
Knud Frederik Vilhelm Hannibal Melbye was born on 14 May 1824 in Elsinore, Denmark. He first trained to become a merchant but then turned to painting, studying under his older brother Anton, already an established marine painter, and attending the Royal Danish Academy of Fine Arts from 1844 to 1847. He also took private classes in perspective drawing with Carl Dahl.
In 1847, he went on his first journey, to Iceland aboard the corvette Valkyrien, and the following year he traveled to Paris by way of Desseldorf. In Paris he studied with Theodore Gudin (1802 - 1880) before returning to Denmark in 1849.
From 1853 to 1866, he lived in London and it was here he changed his name from Vilhelm to Wilhelm.
He was appointed Professor at the academy in Copenhagen in 1880 but died in 1882 in Roskilde. He is interred at Assistens Cemetery in Copenhagen.
