[2] His first work, War, was exhibited in 1871, and was followed by a long series of humorous groups, including Children Dancing, Say Good Morning, The Lucky Number and; An Accident (1875).

[1] Other notable works include his Brabo Fountain in Antwerp (1886), Robbing the Eagles Eyrie (1890), Drunkenness (1893), The Triumph of Woman, The Bitten Faun (which created a great stir at the Exposition Universelle at Liège in 1905), and The Human Passions, a colossal marble bas-relief, elaborated from a sketch exhibited in 1889.

[1][4][5] Lambeaux didn't escape the wrath of art critics when he showed a life-size model of Temple of Human Passions at the Salon Triennial in Ghent in 1889.

The sculpture managed to attract such fury and uproar that in 1890 the journal L’Art Moderne described the work as follows: [It is] a pile of naked and contorted bodies, muscled wrestlers in delirium, an absolute and incomparable childish concept.

[4][5] In 2006 the association "ASBL Musée Jef Lambeaux" was set up to promote the creation of a museum dedicated to the artist in Saint-Gilles, Belgium.
