The sculptor Henry Hugh Armstead coordinated this massive effort among many artists of the Royal Academy, including Thomas Thornycroft (carved the "Commerce" group), Patrick MacDowell (carved the "Europe" group, his last major work), John Bell (carved the "America" group), John Henry Foley (carved the "Asia" group and started the statue of Albert), William Theed (carved the "Africa" group), William Calder Marshall, James Redfern (carved the four Christian and four moral virtues including "Fortitude"), John Lawlor (carved the "Engineering" group) and Henry Weekes (carved the "Manufactures" group). The Scottish sculptor William Calder Marshall carved the "Agriculture" group. The figure of Albert himself, although begun by Foley, was completed by Thomas Brock, in what was Brock's first major work.
