Johannes Hermanus Barend Koekkoek (6 July 1840, Amsterdam - 24 January 1912, Hilversum) was a Dutch marine artist. He signed his paintings, and is perhaps better-known as, Jan H. B. Koekkoek.
Most of his early works are in a style resembling his father's. Later, in 1864, he moved to Hilversum, where he came under the influence of the Laren School, then adopted stylistic elements from the Hague School. As a result, he came to favor relaxed scenes from the lives of fishermen and their families, rather than dramatic ocean views with ships.
He was married in 1877. Following family tradition, he tutored his son, Gerardus Johannes [de], who also painted landscapes and maritime scenes.[1]
