Jean Wiener was a French pianist and composer.

Le Bœuf sur le toit is the name of a celebrated cabaret-bar in Paris, founded in 1921 by Louis Moysés. It was originally located at 28, rue Boissy d'Anglas in the city’s 8th arrondissement. It was notably the gathering place for the avant-garde arts scene during the period between the wars. Maurice Sachs chronicled it in his 1939 book Au temps du Bœuf sur le toit. Currently it is located at 34, rue du Colisée, having moved five times within the 8th arrondissement. The current building dates from the 18th century.
