Here can be found a set of course lectures in an early PowerPoint format, as developed by Pierre Gy around the turn of the millenium and much used by him up until  ca. 2005.

They are still of significant value even 20 years later because of their historical documentation of how an overview and salient concepts in the Theory of Sampling were originally introduced, characteristically illustrated with many practical examples and industrial cases; they also document Gy’s typical teaching approach with many hand-drawn humorous illustrations a.o.  

Note Pierre’s love for Norway expressed in the additional chapter X, which he used extensively after his first visit.
