John Wallis, who is also credited with several trigonometry contributions, invented the number line in 1695. By so doing, he helped people understand negative numbers better.
The concept of a number line has been used by mathematicians for centuries, so it is difficult to attribute its invention to a specific individual. However, the number line as we know it today was popularized by a German mathematician named Georg Cantor in the late 19th and early 20th centuries. Cantor's work on set theory and the continuum helped to solidify the use of the number line as a visual representation of the real numbers.
