Alfred Tarski is often named among the four greatest logicians of all time. He admired  Charles Sanders Pierce for his great work in Logic of Relations. He worked on the deductive system, theory of definability, logical consequence, and logic of Algebra. He developed an abstract theory of logical deductions that resembles some properties of logical calculi in 1930. Some other admirable achievements are theories of truth, logical constraints, and philosophy.

Kurt Godel

The nickname “Mr. Why” was given to him, due to his immense curiosity during his childhood. Kurt adopted the idea of mathematical realism during his days at the University of Vienna.  He mastered university-level in mathematics at the age of 18 years.
