Renier Meganck (Brussels, baptised on 14 September 1637 – Vienna, 27 November 1690) was a Flemish painter and printmaker known for his landscapes and still lifes. After training in Brussels and working in Ghent, he emigrated to Vienna where he was active as a painter to the Imperial court and an art dealer. His patrons included Karl Eusebius, Prince of Liechtenstein who was the founder of the Liechtenstein collection.
Meganck was born in Brussels where he was baptised in the Church of Our Lady of the Chapel on 14 September 1637. His parents were Anton (Antoni) Meganck and Magdalena van Grimberghen. In 1656 he became a pupil of Leo van Heil in Brussels. Leo van Heil was a canvas painter and miniature painter as well as an architect. After completing his studies with van Heil, Meganck was recorded in Ghent between 1661 and 1669 where he had become a master of the local Painter’s Guild.
By 1671 Meganck had moved to Vienna where he resided for the rest of his life. In Vienna he likely first worked in the workshop of Franciscus van der Steen, a compatriot from Antwerp. Franciscus van der Steen was one of the many artists of the Southern Netherlands who had followed Archduke Leopold Wilhelm, the art loving governor of the Southern Netherlands, upon his return to Vienna in 1656. Franciscus van der Steen was principally active as a reproductive engraver. Meganck is first recorded in Vienna in 1671 when he acted as a witness and sealed the last will of Franciscus van der Steen. Van der Steen died not much later in early 1672.
In Vienna Meganck enjoyed high patronage and he was appointed painter to the Imperial court ('kaiserlicher Kammermaler'). Karl Eusebius, the second Prince of Liechtenstein, became a prominent patron of Meganck. The prince is regarded as the founder of the renowned Liechtenstein collection, which forms the basis of the collection of the Liechtenstein Museum. Meganck did not only sell his own paintings to the Prince buy also acted as the Prince's agent in the purchase of works by other artists. It is known that Meganck arranged for the sale of four landscapes by the Dutch painter Hans de Jode to the Prince.
Meganck died in Vienna on 27 November 1690.
Meganck was mainly known as a landscape painter but he also painted the occasional hunting still life and vanitas still life. He was further active as an etcher. Six engravings of mountain landscapes by him are recorded.
