Sievier showed an early talent for drawing, and studied under
John Young and
Edward Scriven, before attending the
Royal Academy Schools from 1818. His speciality was portrait engravings, though he also did other works, including subjects from
William Etty (whose portrait he also engraved). By 1823, however, he had abandoned engraving for
sculpture. His sculpture portrait subjects included
Prince Albert of Saxe-Coburg and Gotha and Sir
Thomas Lawrence (the latter work now in the
Sir John Soane's Museum). His students included
William F Woodington and
Musgrave Watson. Sievier exhibited at the Royal Academy from 1822 until 1844, and his output there included several busts, figure subjects, gravestones and monuments. His first studio was in
London's
Southampton Row; in 1837, he relocated to Henrietta Street, near
Cavendish Square, and he had a separate residence in
Upper Holloway.
