Malcolm Sargent
As an orchestra conductor Sargent was not always popular.  He made many enemies with a remark he made in 1936 when he said that orchestral musicians should not have a secure “job for life” but should give their “lifeblood with every bar they played”.  Sargent had only just recovered from a long illness himself, during which time the musicians had given him support, so they were very annoyed when he said this.
