Carl Fredrich gauss was instrumental in creation of normal distribution. Due to his keen interest in mathematics of astronomy to obtain the orbit of a planetoid named Ceres, he used method of least squares which is a technique for experimental error.

In this method, x represents the error between true value and the value which obtained by experiment.

While theorizing the probability of a small error higher than that of a larger error Gauss came up with normal distribution to explain the probabilities of the random errors.
