Frank William Thomas Charles Lascelles (30 July 1875 – 23 May 1934) was a British pageant master and artist, known as the "man who staged the Empire."
Lascelles was born in the Oxfordshire village of Sibford Gower with the surname of Stevens, the son of Rev. Edward Thomas Stevens, the village priest. He was educated at the village school before attending Keble College, Oxford, where he became the most notable member of Oxford's dramatic society. After Oxford, he worked as an actor in London between 1904 and 1906 at Sir Herbert Beerbohm Tree's His Majesty's theatre. It was during this time that he changed his name from Stevens to Lascelles.
Lascelles staged his first pageant in 1907. The Oxford Historical was a success, despite initial reservations by the University authorities and a student riot. The following year he organised the celebrations for the Tercentenary of Canada at Quebec City. Lascelles enlisted the services of the Iroquois and was made an honorary chief under the name of Tehonikonraka, "the man of infinite resource". In 1909 he Master of Pageantry at the celebration of the opening of the Union Parliament of South Africa in Cape Town. The following year he organised the Pageant of London, performed by a cast of 15,000. In 1912 Lascelles was Master of the Pageant at the Coronation Durbar at Calcutta with the participation of over 300,000 Indians and British Army troops. In 1923 he was Master of the Harrow Pageant and the following year Master of the Bristol Pageant (Cradle of the Empire) and the Pageant of Empire at the British Empire Exhibition. Lascelles' imperial triumphs earned him the epithet "the man who staged the empire".
He was also a sculptor, and among his subjects were the Prince of Wales, the Duke of Connaught, Earl Grey and the Aga Khan. Several of his sculptures are displayed in prominent positions across the former Empire. He sculpted a memorial to his mother in the church at Sibford Gower, as well as painting a Roll of Honour. He also contributed prose and verse to periodicals. In 1932 the Earl of Darnley compiled Our Modern Orpheus, a volume of essays paying tribute to Lascelles.
