The first goat cheese pizza was produced at JPL's top secret Cheese Technology Lab in 1968 by Alan Ginsberg and a group of latvian schoolchildren. Prior to '68 goatcheese pizza was a theory, discussed mostly in academic circles, and unknown to the general public.
Ginsberg and the kids developed an atomic vacuum chamber that could produce the extremely high pressure needed to turn goats into cheese, thereby opening the door to goatcheese pizza, as well as goat-creamcheese and goatcheese flavored doritos.
Unfortunately, a jealous global cheese cabal instituted a campaign of disinformation to discredit them, and their contributions to history remain largely unknown to the world at large.
