Ludwig van Beethoven's Piano Concerto in E flat major, WoO. 4, is one of his earlier works, written in 1784 when he was only 14. Only the solo piano part survives today, although there are some indications in the manuscript for orchestral cues. On the occasions when the work has been performed, the orchestral part has had to be arranged beforehand. The concerto is sometimes referred to as Piano Concerto No. 0, as it came before all of Beethoven's other piano concertos. It is rarely performed. Pianists Howard Shelley, Ronald Brautigam and Philippos Tsalachouris, as well as the Swiss musicologist and composer Willy Hess, have each made their own reconstructions of the concerto.

John Thomson FRGS was a pioneering Scottish photographer, geographer, and traveller. He was one of the first photographers to travel to the Far East, documenting the people, landscapes and artefacts of eastern cultures. Upon returning home, his work among the street people of London cemented his reputation, and is regarded as a classic instance of social documentary which laid the foundations for photojournalism. He went on to become a portrait photographer of high society in Mayfair, gaining the royal warrant in 1881.
