The spiral wasn't created by anyone since you can see spirals in nature, such as shells and plants.
If you are interested in who studied spirals, that would be Archimedes of Syracuse, dated back about 225 BC. He did studies and came up with the Archimedean spiral, also known as the arithmetic spiral).
