As a new film starring Meryl Streep is released, Clemency Burton-Hill finds out what made Florence Foster Jenkins so popular - and inspirational.
Florence Foster Jenkins was a 20th-Century US socialite and music-lover who styled herself as an operatic coloratura soprano and became a sensation.

Her extraordinary story has long held a fascination for writers, directors and musicians.
