Heinrich Gentz (5 February 1766 â 3 October 1811) was a German Neoclassical architect.
He was the second son of Johann Friedrich Gentz(e), master of a mint in the city who became general mint director in Berlin in 1779 and was friends with Gotthold Ephraim Lessing, Immanuel Kant, Moses Mendelssohn and Christian Garve. On his mother's side Heinrich was a cousin of Jean Pierre Frédéric Ancillon, a government minister and tutor to the Prussian princes. Among his brothers, Friedrich became a publicist and historian based in Vienna as well as the closest member of Prince Metternich's staff, whilst Ludwig became secretary to the Prussian privy council, Minister for War in the Prussian Finance Ministry and a friend of Friedrich Gilly (marrying Gully's wife's sister).
He was born in Breslau (now Wrocà Âaw in Poland but then part of the Kingdom of Prussia) and trained as an architect from 1783 to 1790 at the Berliner Kunstakademie under Carl von Gontard. He took a grand tour to Italy between 1790 and 1795, including three and a half years in Rome and a long period studying Magna Grecia ruins in Sicily, meeting Aloys Hirt in Italy and writing a detailed report of these travels. He then worked at the royal building office in Berlin and from 1796 onwards also at the Kunstakademie.
In 1799 he was one of the founder members of the Berliner Bauakademie, where he taught urban planning, and married Henriette Louise Philippine Holtzecker (1778âÂÂ1814), daughter of Georg Holtzecker (a Berlin merchant) and Louise Friederike Sieberdt - they had no children. He was released from his posts in Berlin thanks to Johann Wolfgang von Goethe in 1801 and moved to Weimar, where he worked for Karl August on the Residenzschloss and other ducal buildings in Weimar and Bad Lauchstädt. While in Weimar Gentz became close friends with Goethe and got to know Friedrich von Schiller and Christoph Martin Wieland.
In 1803 he not only returned to Berlin but was made a member of the Kunstakademie's senate (becoming a full member in 1805 and acting as the Kunstakademie's secretary from 1809 onwards). As chief architect to the royal court, in 1810 he became the first director of the Berlin Palace building commission. Also in 1810 he joined with Hirt and Wilhelm von Humboldt to convert the Prinz-Heinrich-Palais into a university and joined the Gesetzlosen Gesellschaft zu Berlin, dying in the city the following year.
