There is some debate about who was first, Berann or Novat, but either way, this was 40 years before James Niehues from the article even started working in this style.

Since I've been skiing this has been how I've experienced all the terrain. His maps just are skiing to me. But, interestingly, with the rise of smartphones/gps apps like Slopes and the late lamented Fatmap have started to move the ski world towards 3d terrain maps and away from these artistic maps.
I have a side project I've been meaning to dust off that translated GPS coordinates to locations on Niehues maps. I got it working reasonably well but the distortions were significant enough that it needs a lot of control points to do the mapping.
There's also something functionally superior to having someone who created an aesthetic and standard across ski maps.. someday they'll evolve and we'll have something different, but being able to show up to a new ski mountain and immediately understand the map: it's excellent UX.
Honestly it was a little disappointing -- the maps in the book are just the paintings of the mountains/terrain, no trail/lift/amenity markings, and thumbing threw it for a little while, they all kind of look exactly the same.
