Jean Des Roches
Jan or Jean Des Roches (1740–1787) was a Dutch-born educator, historian and linguist in the Austrian Netherlands.

Life
Des Roches was born in The Hague in 1740 and was baptised at Voorburg on 1 March that year, with the baptismal record indicating his parents were not married. His mother, Louise Rottevrel, was in domestic service. Des Roches was apprenticed to a pastry chef, but spent as much time as he could reading. 

In 1757 he read a newspaper advertisement for an assistant schoolmaster to teach Dutch in the countryside near Aalst and set off to apply. Arriving in Antwerp he was taken on in a primary school there, which was run by a German Augustinian who taught him Latin. In 1761 he published a Dutch grammar, Nieuwe nederduytsche spraek-konst, that went through three editions in the first year, and in 1763 a French grammar, Nieuwe fransche spraek-konst, which continued to be reprinted until 1801. The school where he was teaching closed in 1765, and Des Roches found employment as a private tutor.

On 13 April 1773 he became a member of the newly founded Imperial and Royal Academy of Brussels, on the strength of his publications on Belgian history, and in March 1776 he was appointed its permanent secretary. In 1777 he was also appointed secretary to the Commission Royale d'Études, set up to reform education in the Austrian Netherlands. In 1786 he travelled to Austria, where he spent six months visiting schools to learn about the new methods of education there. He returned to Brussels in March 1787 as Inspector General of Schools, but died on 20 May that year.
