Educated at the Académie Royale des Beaux-Arts in Brussels (1859–1868), van der Stappen's contribution to the Brussels Salon was "The Faun's Toilet" of 1869, and thereafter he began to produce work of a high and novel order in every class of sculpture, and soon, along with Paul de Vigne, became recognized as the leader of the section of the new Belgian school of sculpture which infused models derived from Greek and Roman models and the art of the Italian Renaissance with naturalistic detail and fleeting action.[1]
His best-known funeral monuments are those to Alexandre Gendebien (1874) and Baron Coppens, at Sheel (1875). His statues include William the Silent, set up at the Petit Sablon Square, and two in the Brussels Museum, The Man with the Sword, and "The Sphinx". The bronze group Ompdrailles was acquired by the Belgian government (1892).[1]
In 1893 the sculptor began his collaboration with Constantin Meunier for the elaborate decoration of the Botanical Garden of Brussels, coordinating many other sculptors for the production of some 52 sculptures for its grounds. The result of the connection may be seen in the group The Builders of Cities which is strongly imbued with the feeling and types of Meunier's sympathetic figures of workers.[2]
