Samuel Sebastian Wesley
Samuel Sebastian Wesley (born London, 14 August 1810; died 19 April 1876) was an English organist and composer.  He was the greatest English composer of church music of his day. He lived at a time when the standard of music in England had become very bad.  He did a lot to improve it, especially church music.  He had a hard life earning enough money.  This was largely his own fault: he was a difficult man with a bad temper and often argued with his employers.
