In page Herman Frederik Carel ten Kate (artist):

"

His career started in 1837. Some of Ten Kate's paintings, which were very popular with the public, depicted interior scenes of guard rooms with Spanish or Dutch soldiers in uniform. His colouring was rich, and his brushwork was careful. Ten Kate's paintings were exhibited in the museums in The Hague (1867, 1869), Belgium, Germany, Italy, France (1840-1841), Amsterdam (1868), and Haarlem.[1] He was Director of The Academy of Arts (1860s).[2] During wartime, there was a decline in the sale of his military themed art work so he shifted his emphasis to landscape paintings. His art work titled Un counseil deguerre sold in June 1870 but his next painting didn't sell until February 1872.[3]
