A son of Octar H. Copson, a fruit painter for Royal Worcester porcelain, Arthur Paul was born in 1881, in Worcester, England. He immigrated in 1895 to the USA, lived in Grand Rapids, MI, then Wyoming, MI; then traveled to France, England, Montreal and Quebec. He painted in all of these locations and studied at the Julian Academy in Paris.
By 1900, he was decorating furniture at Oriel Cabinet Company, a Grand Rapids fine cabinets manufacturer. His father was the art director at the same company at the same time, while his brother and sister were also decorators, which may be considered prove that Octar likely trained them all from early on.
Paul later trained locally as an art student in Grand Rapids however by 1900 the family was in residence at a little known art colony called Beckmaze which is in Wyoming, MI, just a few miles south of Grand Rapids. At this colony, he was exposed to the works of other artists including George H. Ford and others. One of the more famous friends of the Copson family was Mathias Alten. At least one of Alten's pieces ended up in the Copson collection which was donated to the Horner Museum in Benton County, Oregon.
In 1914, Paul registered with the Canadian Regiment and for some reason, he said he was born in 1884 (his brother's birth year). He died two years later in 1916.
