Scene Release

Denis O’Brien was brought up in Dublin 4, in Ballsbridge.

His father Dano was an entrepreneur from Cork and had a business selling equine products. His mother Iris is from Co Armagh. Denis O’Brien later said he learned about business from his father and gained a sense of social justice from this mother.

He spent two years on the road in the US selling products for his father – it was there that Denis O’Brien had the idea for one of his first ventures.
