Roderic O'Conor (17 October 1860 – 18 March 1940) was an Irish painter who spent much of his later career in Paris and as part of the Pont-Aven movement.

[1] Born in Milltown, Castleplunket, County Roscommon in Ireland,[1] O'Conor attended the Metropolitan School and Royal Hibernian Academy early in his career.

[4] He studied at Ampleforth College, and like his classmate, Richard Moynan, travelled to Antwerp before moving to Paris to gain further experience.

Both portraits are unflattering: O'Brien is "a failure whose bitterness has warped his soul so that, unforgiving of the success of others, he lashes out at any artist of talent", while Clutton is "a sardonic painter who is most cheerful when he can find a victim for his sarcasm".

Landscape, Cassis, an oil-on-canvas, was painted by O'Conor in the south of France in 1913 and sold at Sotheby's for significantly higher than the estimated price.
