They might have used and understood this Study, But the actual discovery of the golden ratio can be lead back to the ancient Greeks and the Pythagoras. The greek mathematician Euclid of Alexandria mentioned the golden mean.
Golden ratio in geometry & mathematics
Not only is the golden ratio a value in the mathematics...
Furthermore, the Golden Ratio can be found in different kinds of shapes. This goes on from the usual rechangle, through different kinds of triangles and to the very complicated shapes like the pentacle.
A rectanle is a Golden rectangle when the sides are in the 1:0,618 proportion. Below is an example of this kind of shape.
