E. Adveno Brooke
Born in 1821, Brooke appears to primarily have been a landscape painter who strayed into the realm of painting gardens. He is known to have exhibited perfectly conventional rural scenes, farms, riverscapes and fishing subjects at various galleries including the Royal Academy between 1844 and 1864.
There are only occasional notices for these in the press but even they are mainly about the exhibition of the original sketches and paintings for the book. It is fair to say Brooke's doesn't seem to have taken the art world by storm with his other output.
Brooke lived to be nearly 90, dying in Battersea in 1910, but of the rest of his life there appears to be no record. There are no interviews in newspapers or contemporary magazines, and little or no academic work on him since, and even the dates of his birth and death are usually merely a footnote to mentions of his only book.
