Thomas Attwood (23 November 1765 – 24 March 1838) was an English composer and organistIn 1796 he was chosen as the organist of St Paul's Cathedral, and in the same year he was made composer of the Chapel Royal. His court connection was further confirmed by his appointment as musical instructor to the Duchess of York, and afterwards to the Princess of Wales. In January 1806, he played his own composition, Grand Dirge, on the organ for the funeral of Lord Nelson, the only piece specially written for the occasion. For the coronation of George IV, he composed a setting of the traditional anthem I was Glad, which was also used at the coronations of King William IV and Queen Victoria. The king, who had neglected him for some years on account of his connection with the Princess of Wales, now restored him to favour, and in 1821 appointed him organist to his private chapel at Brighton.
