Namnet nämns på bl.a. en globkarta utgiven i Augsburg 1786. 'Iean George Probst Fils'.
1655-1694.
Direktör för lantmäteriet, tog initiativet till den första svenska Generalkartan.
At the age of 28, appointed director (later director-general) for the National Land Survey. Offices were a room at the royal palace, 'but in autumn, winter and spring, maps never could be stored there because of the moisture, snow and rain that drift in through the leaky walls'. Wrote poetry with same success - 200 years later the works were deemed 'currently unpalatable'. In the early 1690s worked on Stockholm's Outer archipelago, until then poorly represented on charts. For security reasons, the lise of maps was restricted. His maps first round real use a hundred years later as underpinning for Sweden's Marine Atlas (Sveriges Sjöatlas).
