Platon Sergeevich Poretsky (born October 3, 1846, Elisavetgrad - August 9, 1907) was a noted Russian astronomer, mathematician, and logician. Graduated from Kharkov University he worked in Astrakhan and Pulkovo. Later being an astronomer at Kazan University after an advice of his older colleague Professor of Mathematics A.V. Vasiliev at Kazan University (father of Nicolai A. Vasiliev) to learn works of Boole Poretsky developed "logical calculus" and through specific "logical equations" applied it to the theory of probability. Thus, he extended and augmented the works of logicians and mathematicians George Boole, William Stanley Jevons and Ernst Schröder.
