Very, very good marketer, Fredrick the Great. But not a patch on Ataturk.

I've heard this attributed to several other kings, but doing a bit of historical research, it seems to be Fredrick the Great.

Fredrick the Great of Prussia was very, very keen for the Germans to adopt the potato and to eat it, because he realized that if you had two sources of carbohydrate, wheat and potatoes, you get less price volatility in bread.
