In the mid-nineteenth century Giacomo Meyerbeer dominated the operatic world. The first Jewish composer to achieve international fame, he staged his grand operas in France. His second work, Les Huguenots, became the first opera to reach 1,000 performances at the Paris Opéra. He was born in Berlin in 1791 as Meyer Beer, the eldest son of Jacob and Amalia Beer. As European Jews emerged from the ghetto, his wealthy parents took a leading role in creating a more integrated Jewish identity. Jacob became a pioneer of Reform Judaism, while Amalia held a glittering musical salon. His brother Wilhelm built an observatory, where he and his scientific partner, Johann Mädler, made the first accurate maps of the moon and Mars. A milestone in the history of astronomy. Later Wilhelm became a railway entrepreneur, a banker and a politician. The youngest son Michael was a dramatist and poet who died at the age of 33. His third play was admired by Goethe, who staged it at Weimar. This biography reveals the story of a remarkable family who fought prejudice and intolerance to become role models for their contemporaries, and whose lives illuminate a crucial and formative period in German-Jewish history
