In June 1842 Mendelssohn was twice received by Queen Victoria at her palace in London. Mendelssohn thanked the Queen by dedicating his "Scottish Symphony" to her. He continued to conduct in Leipzig and helped to make Berlioz’s music famous in Germany. He became director of the new Conservatoire in Leipzig. In Berlin the king asked him to provide incidental music for Shakespeare's play " A Midsummer Night’s Dream ". He had already written some of this music 17 years earlier but now he finished it and performed it in 1843.
