Petrus Schenck, or Pieter, or Peter Schenk the Elder was a German engraver and cartographer active in Amsterdam and Leipzig.
The engraver and map publisher Peter Schenk was born in 1660 in Elberfeld. He moved to Amsterdam in 1675 and became a student of Gerard Valck specializing in mezzotint. Valck was married to Maria Bloteling, the sister of the Amsterdam engraver Abraham Bloteling. In 1687 Schenk married Gerard's sister Agatha Valck. In 1694, together with Valck, he bought some of the copperplates of the artdealer and cartographer Johannes Janssonius. Along with Valck and Bloteling, he produced prints for the London market, though it is not known if he ever went there with them.
Until 1700 he lived in the Jordaan, then he moved to Dam Square or to Leipzig, where he opened a shop, selling maps and art. He was a regular visitor to the trade fair Leipziger Messe in Leipzig, where he died. He had three sons who became engravers. His eldest son Peter Schenk the Younger was also a noted cartographer and art dealer who continued his father's shop in Leipzig. His sons Jan and Leonard stayed in Amsterdam and probably continued their father's workshop. His daughter Maria married Leonard Valck, the son of Gerard, who continued Gerard's workshop.
