Joseph Bertrand

Joseph Bertrand was a 19th-century French mathematician renowned for his work in analysis and number theory. He contributed to the understanding of prime numbers and is best known for Bertrand's Postulate, which states that for any number greater than 1, there is always a prime number between that number and twice its value. His work helped deepen the understanding of the distribution of prime numbers and influenced the development of modern mathematical analysis. Bertrand's contributions are foundational in the study of primes and continue to be significant in number theory today.
