Frederik de Winne (born 28 May 1985 in Ghent) is a Belgian footballer who plays as a right back for KVC Jong Lede.
 His prior clubs included Belgian Pro League team Lokeren and Belgian Second Division team OH Leuven.
Liévin De Winne (Ghent, 24 January 1821 - Brussels, 13 May 1880) was a Belgian portrait painter who painted the official portrait of Leopold I on which the first postage stamp of Belgium was based.
Dorothea Tieck (March 1799 – 21 February 1841) was a German translator, known particularly for her translations of William Shakespeare.
 She was born in Berlin, Brandenburg, as the daughter of Ludwig Tieck, and collaborated with her father and his Romantic literary circle, including August Wilhelm Schlegel and Wolf Heinrich Graf von Baudissin.
 She completed the translation of Shakespeare's works her father had begun with Schlegel and Baudissin, and worked also on Miguel de Cervantes and other Spanish writers.
In geometry, a Schlegel diagram is a projection of a polytope from formula_1 into formula_2 through a point beyond one of its facets or faces.
 The resulting entity is a polytopal subdivision of the facet in formula_2 that is combinatorially equivalent to the original polytope.
 Named for Victor Schlegel, who in 1886 introduced this tool for studying combinatorial and topological properties of polytopes.
 In dimensions 3 and 4, a Schlegel diagram is a projection of a polyhedron into a plane figure and a projection of a 4-polytope to 3-space, respectively.
 As such, Schlegel diagrams are commonly used as a means of visualizing four-dimensional polytopes.
Maxime De Winne (born 22 June 1977) is a Flemish actor and theatre producer.
Frank, Viscount De Winne (born 25 April 1961, in Ledeberg, Belgium) is a Belgian Air Component officer and an ESA astronaut.

 He was the first ESA astronaut to command a space mission when he served as commander of ISS Expedition 21.
 ESA astronaut de Winne serves currently as Head of the European Astronaut Centre of the European Space Agency in Cologne/Germany (Köln).
Expedition 35 was the 35th long-duration mission to the International Space Station (ISS).
 The expedition started 13 March 2013, and marked the first time a Canadian astronaut – Colonel Chris Hadfield – was in command of the station.
 Expedition 35 was also only the second time an ISS crew is led by neither a NASA astronaut, nor a Roscosmos cosmonaut, after Expedition 21 in 2009, when ESA astronaut Frank De Winne was in command.
Passacaille records is a Belgian classical music record label, owned by Musurgia BVBA, based in Halle, Belgium.
 The company's artistic director is the flautist and flute-maker Jan De Winne.
Hans Wilhelm Schlegel (Überlingen, 3 August 1951) is a German physicist, an ESA astronaut, and a veteran of two NASA Space Shuttle missions.

 The expedition began on 30 October 2009, with Frank de Winne becoming the first ESA astronaut to command a space mission.
