Who was the 18th century statistician and consultant to gamblers that discovered the normal curve?

de Moivre reasoned that if he could find a mathematical expression for the smooth curve that came about when the number of binomial events (coin flips) increased, he would be able to solve problems such as finding the probability of 60 or more heads out of 100 coin flips much more easily. The curve he discovered is now called the "normal curve."

Why was the normal curve an important development?

For example, one of the first applications of the normal distribution was to the analysis of errors of measurement made in astronomical observations. Galileo in the 17th century noted that these errors were symmetric and that small errors occurred more frequently than large errors.

It has a relatively simple formula.
true
Many natural phenomena are at least approximately normally distributed.
true
Many inferential statistics can only be computed with a normal distribution.
Who is responsible for the central limit theorem?

Laplace derived the central limit theorem. Adrian and Gauss developed the formula for the normal distribution.
