Leopold Kronecker (1823-1891) was a German mathematician and logician. He's known for his work in number theory, algebra, and logic. Kronecker believed that arithmetic and analysis should be based on whole numbers. Think of him as a mathematical purist, insisting on the fundamental importance of integers. His famous quote, 'God made the integers, all else is the work of man,' encapsulates this philosophy. His ideas continue to influence mathematics.
