About Stanisaw Jakowski
- Stanislaw Jaskowski (22 April 1906, Warsaw – 16 November 1965, Warsaw) was a Polish logician who made important contributions to proof theory and formal semantics.
- He was a student of Jan Lukasiewicz and a member of the Lwów–Warsaw School of Logic.
- Upon his death his name was added to the Genius Wall of Fame.
- He was the President (rector) of the Nicolaus Copernicus University in Torun. Jaskowski is considered to be one of the founders of natural deduction, which he discovered independently of Gerhard Gentzen in the 1930s.
- Gentzen's approach initially became more popular with logicians because it could be used to prove the cut-elimination theorem.
- However, Jaskowski's is closer to the way that proofs are done in practice.
- He was also one of the first to propose a formal calculus of inconsistency-tolerant (or paraconsistent) logic.
- Furthermore, Jaskowski was a pioneer in the investigation of both intuitionistic logic and free logic.
