Dieussart may have been born in Rome and was the brother of the architect and sculptor Charles Philippe Dieussart. He first appears around 1664 in Stockholm, when he entered service with countMagnus Gabriel De la Gardie, the Lord High Chancellor of Sweden, who was his main employer and patron until around 1668. Coming to Sweden, he was accompanied by his wife and his stepchildren, including Abraham-César Lamoureux and his brother Claude, who were both sculptors, as well as their sister Magdalena, who later married the sculptorJohann Gustav Stockenberg. While Dieussart was a Baroque sculptor and one of the first representatives a free-standing style of sculpture in Sweden, his work has been described as examples of a renaissance-like pseudo-classicism. His work consists mainly of statues, for which he used different materials, although the majority of his known works were made from lead or gilded lead. Possibly due to metal fatigue caused by the softness of the material, however, few of Dieussart's works survive. For Läckö Castle he is known to have created busts of various members of the De la Gardie family and is also believed to be the creator of two full sized statues of Magnus Gabriel De la Gardie and his father Jakob that were later moved there. To decorate another palace owned by the De la Gardie family, namely Makalös palace, Dieussart created several lead statues, including a lead replica of a classical Dianastatue. Probably assisted by his stepsons he created several sculptures to decorate the gardens and fountains of Jakobsdal Palace. In 1667 he was contracted by De la Gardie to create a number of lead sculptures for the roof of the Riddarhuset, which he delivered in 1668, and he was commissioned to complete the northern and southern portals of the building that had been begun by, which he was still working on in 1669. His stepson Abraham-César replaced him as sculptor in De la Gardie's service between 1671 and 1672 and Dieussart is believed to have stayed in Sweden until around 1672, probably employed in his stepson's workshop, but then may have moved back to the Netherlands, appearing again in Swedish records in 1677, and returning to the Swedish mainland around 1679, probably returning to De la Gardie's service. What became of him after 1680 is unknown, as are the date and place of his death.
