Peter Joseph Lenné
Peter Joseph Lenné (the Younger) (29 September 1789 – 23 January 1866) was a Prussian gardener and landscape architect. As director general of the Royal Prussian palaces and parks in Potsdam and Berlin, his work shaped the development of 19th-century German garden design in the Neoclassical style. Laid out according to the principles of the English landscape garden, his parks are now World Heritage Sites.
