He studied art at St. Martins School of Art and later at one of the Royal Academy schools. Though a popular and successful artist, he never featured in any major national exhibitions during his lifetime (though he did exhibit in Canada and the USA), and not much is known about his life.
His works show not only the influence of the impressionist school, but also owe something in technique and subject matter to his well-known contemporary Benjamin Williams Leader.
Parker was undoubtedly at his best when painting country scenes; the skill with which he represents the surrounding landscape is particularly commendable, especially in a more prestigious work such as this. Parker’s style could be described as atmospheric; his canvases have a powerful sense of movement, conjured by the vigour of his brushwork.
He also worked for a time as an illustrator for the Illustrated London News.
Parker also painted under the names H.D. Hillier or H.D. Hillyer.
