William Henry ('Will') Dyson was an Australian illustrator, artist and political cartoonist who achieved international recognition. He initially worked as a freelance artist in Australia, developing a specialty as a caricaturist, notably in The Bulletin magazine. In 1909 Dyson married Ruby Lindsay and the couple settled in London soon afterwards. As cartoonist for The Daily Herald newspaper, Dyson became widely known as an illustrator and commentator supporting progressive social reforms in Britain. His cartoons were often controversial, tackling difficult issues such as poverty, inequality and war, and were characterised by their biting wit and artistic impact. At the outbreak of World War I Dyson directed his scathing artwork at German militarism. In 1916 he applied to join the Australian forces at the Western Front as an artist. He was appointed an honorary lieutenant and joined the Anzac troops in France in January 1917. By the following May his appointment as Australia's first official war artist was formalised. After the death of his wife in March 1919 Dyson went through a difficult emotional period, during which his artistic output suffered. In late 1924 he returned to Australia after accepting a contract to work for the Herald publishing group in Melbourne. Dyson returned to England in 1930. He died in London in 1938, aged 57.

The Bulletin was an Australian weekly magazine based in Sydney and first published in 1880. It featured politics, business, poetry, fiction and humour, alongside cartoons and other illustrations.
