Early life and education

He was born at St Mary's Hospital, London in Westminster, London, the fourth child and eldest son of Charles Spencer, 9th Earl Spencer, and his first wife, Victoria Lockwood. A nephew of Diana, Princess of Wales, and a first cousin of the Prince of Wales and Prince Harry, Duke of Sussex, he is the heir apparent to the Spencer earldom.
A year after he was born, his family moved to Cape Town in South Africa, where he grew up.
Lord Althorp was a pupil at Diocesan College in Cape Town, and later enrolled at the University of Edinburgh. He graduated from Arts Educational Schools in London, on 6 September 2022, as the valedictorian.

Viscount Althorp

English male primogeniture law dictates that Lord Althorp, not his elder sister, Lady Kitty Spencer, who is her father's firstborn child, will inherit the Spencer title. Property is divisible separately, but most peers choose to keep property and title combined. As heir to the Spencer earldom, Louis Spencer is expected to inherit the estimated £100 million Althorp estate under the tradition of male primogeniture, despite having three older sisters.

Career

As of 2025, he is an actor working under the professional name "Louis Lyons". He is currently represented by the Tavistock Wood talent agency.
