The same people who invented the wheel about 6,000 years ago: the Mesopotamians, who loved the number 60. It's a useful and easily divisible number, which made it ideal for both early mathematics and commercial trade. The Mesopotamians passed their base-60 numerical system to the ancient Egyptians, who used it to divide a circle into 360 degrees, Mary Blocksma writes in her book Reading the Numbers.
