Pearson, Carl

The Englishman Carl Pearson (1857 - 1936), son to a lawyer, was an biostatistician and mathematician.

In 1892, he published the book The Grammar of Science, which was recommended by Albert Einstein to his friends. It covered several themes that later became part of the theories of Einstein, such as the relativity of motion to reference frame, the equivalence of matter and energy, physics as geometry, the non-existence of the ether, antimatter, the fourth dimension, and wrinkles in space.

However, his main achievents are in the field of statistics. He developed statistical techniques including the chi-squared test, standard deviation, correlation, and regression.

He lent his name to the Pearson distribution and the Pearson chi-squared test.
