From kings to the X Factor, his namesakes

LOUIS ARMSTRONG

The What A Wonderful World singer (1901-1971) was famous for his rich, throaty tones, capturing the hearts of music lovers all over the world and bringing jazz into the mainstream.

LOUIS XVI

One of the 18 French kings who went by that name, but perhaps also one of the more unfortunate. He was famously married to Marie Antoinette, the last queen of France, and was executed in 1793 during the French Revolution.

LOUIS THEROUX

Famed for his straightforward interview style paired with an uncle-like charm, Louis Theroux is one of Britain’s best-loved documentary makers. Able to encourage people to say the unsayable, his films address issues of social injustice and taboo.

LOUIS VUITTON

The Frenchman started his luxury international fashion brand in 1854. Fans today say the LV monogram sets its products apart from the crowd in an instant – a mark of quality, care and craftsmanship.

LOUIS PASTEUR

The French scientist not only extended the shelf-life of milk by discovering pasteurisation, but he also produced the first vaccine for killer disease rabies. He started the Pasteur Institute in 1887 which researches vaccines and disease to this day.

LOUIS TOMLINSON

The teenage heartthrob charmed the nation on The X Factor, performing solo before linking up with four other contestants to form pop sensation One Direction. He has since forged a solo career. Upon hearing the royal baby news he tweeted: ‘Young Louis, welcome to the world. I’ll take you under my wing lad.’

LOUIS FERRIGNO

Known simply as Lou, the bodybuilder (pictured in his TV role) used his physique to play the Marvel comic book character The Incredible Hulk in the hit show.

LOUIS WALSH

In the music business for decades, the 5year-old Irishman has transformed smalltown musicians into superstars as both a manager and a judge on The X Factor.
