John Lavery (1856–1941) was an Irish painter known for his elegant portraits, atmospheric landscapes, and scenes of modern life. Born in Belfast, he gained international recognition and painted many prominent figures of his time, including members of the British royal family. Lavery worked in a style that blended realism with impressionist influences, often painting en plein air to capture light and movement.

Among his most famous works is a portrait of his wife, Hazel Lavery, which was later used on Irish banknotes from the 1920s to the 1970s—turning her into a lasting symbol of Ireland. The couple supported Irish independence, and their London home was even used for treaty negotiations during the formation of the Irish Free State.
