Who invented binary numbers?

Binary numbers were first fully described by the ancient Indian mathematician Pingala around the 2nd century BCE, who used a binary system in his work on Sanskrit prosody. However, the modern binary numeral system was developed by Gottfried Wilhelm Leibniz in the 17th century, who introduced it in 1679 and connected it to philosophical concepts. Leibniz’s work laid the foundation for the binary system used in digital computing today.
