John G. H. Cantor

John G. H. Cantor was a mathematician known for his work in mathematical logic and set theory. He contributed to understanding how to categorize different sizes of infinity and developed concepts that help clarify the nature of infinite sets. His work helped mathematicians understand that some infinities are larger than others and laid the groundwork for modern set theory, which underpins much of contemporary mathematics. Cantor's ideas have had a lasting impact on how we think about and study the infinite in a rigorous and structured way.
