Baron Pietro Carlo Giovanni Battista Marochetti RA (14 January 1805 – 29 December 1867) was an Italian-born French sculptor who worked in France, Italy and Britain.

[5] Between 1822 and 1830 Marochetti frequently spent long periods in Rome where his mother was resident and where he collaborated with François-Joseph Duret and Antoine Étex and worked briefly at the studio of the Danish sculptor Bertel Thorvaldsen.

One was for a relief panel of the Battle of Jemappes on the Arc de Triomphe and the other for a large marble statue group, the Elevation of Mary Magdalene for the altar of the Church of La Madeleine.

[6] He delayed completing the altar group to create a monumental equestrian statue of Emmanuel Philibert, Duke of Savoy which he donated to the city of Turin.

[6] After the fall of the July Monarchy in 1848, and his subsequent failure to win a seat in the National Assembly, Marochetti followed the French king Louis-Philippe into exile in the United Kingdom.

[1][10][4] From 1864 Marochetti collaborated with Sir Edwin Landseer on the four bronze lions to be placed at the base of Nelson's Column in Trafalgar Square, and cast them at his Sydney Mews foundry.

[1][12] With the support of the exiled Louis-Philippe of France, Marochetti first met Queen Victoria and Prince Albert in 1849 and subsequently received a number of royal commissions.

[1][4] Marochetti's first royal commission in England was for a marble portrait bust of Prince Albert in 1849, which was commercially reproduced in Parian ware by the Mintons company in 1862.

[4] That year Queen Victoria commissioned Marochetti to produce a portrait bust of herself as a birthday gift for Prince Albert and that too was reproduced by Mintons for the retail market.
