Largely organised by Prince Albert, when did The Great Exhibition take place in Hyde Park, London?

The Great Exhibition of the Works of Industry of All Nations or The Great Exhibition, sometimes referred to as the Crystal Palace Exhibition in reference to the temporary structure in which it was held, was an international exhibition that took place in Hyde Park, London, from 1 May to 15 October 1851. It was the first in a series of World's Fairs, exhibitions of culture and industry that became popular in the 19th century, and it was a much anticipated event.

The Great Exhibition was organized by Henry Cole and Prince Albert, husband of the reigning monarch, Queen Victoria. It was attended by famous people of the time, including Charles Darwin, Samuel Colt, members of the Orléanist Royal Family and the writers Charlotte Brontë, Charles Dickens, Lewis Carroll, George Eliot and Alfred Tennyson. Music for the opening was under the direction of Sir George Thomas Smart and the continuous music from the exhibited organs for the Queen's procession was "under the superintendence of William Sterndale Bennett".
