who discovered pi?

No single person discovered pi; it emerged over thousands of years, but Archimedes of Syracuse is usually credited with the first truly rigorous calculation of its value.

Quick Scoop

• Ancient Babylonians and Egyptians were already using rough circle ratios more than 3,500 years ago, so the idea behind pi is very old.

• Archimedes (3rd century BCE) used polygons around a circle to pin pi between 223/71223/71223/71 and 22/722/722/7, so he’s often named as the key figure who “discovered” pi in a mathematical sense.

• Later, Chinese mathematicians like Liu Hui and Zu Chongzhi, and Indian mathematicians like Madhava, pushed accuracy much further with clever geometry and early infinite series.

• The symbol π itself was introduced in 1706 by William Jones and made standard by Leonhard Euler in the 1700s.

So, who discovered pi?

If you need a one‑name answer:

• People usually say Archimedes of Syracuse discovered pi, because he created the first rigorous method to approximate it.🧠

But the more accurate story:

• Pi is a global, cumulative discovery , built from the work of many cultures over millennia, not a single “lightbulb moment” by one person.
