Henriette Ragon (10 June 1918 – 30 April 2015), better known as Patachou, was a French singer and actress, best-known for popularizing Georges Brassens songs by singing them before he became famous.

Born in the 12th arrondissement of Paris, Henriette Ragon began her working life as a typist, then a factory worker, a shoeseller and an antique dealer.

(Their son Pierre Billon had some success as a singer in the 1970s and wrote J'ai oublié de vivre for Johnny Hallyday.)

Sometimes she would collect half-ties (she would snip the neckties of customers reluctant to join in the singing and immediately staple them to the ceiling, a habit which has created a very original decor of the place - hundreds of neckties hanging above) – Thomas Dewey and Errol Flynn were among her victims.

From the beginning of the 1970s she toured Japan and Sweden where 'L'eternal Parigot', with her cheeky Parisian register, was popular.
