Albert Einstein was born in 1879 in Ulm and later grew up in Switzerland, where he also completed his education. He acquired Swiss citizenship, lived for a time in Germany, and spent his final years in the United States. In 1905, he published several fundamental scientific papers, including one on the photoelectric effect, which significantly contributed to the development of quantum mechanics. He also formulated the special and general theories of relativity, which profoundly changed the understanding of space, time, and gravity. In 1921, he received the Nobel Prize in Physics, and his famous equation (E = mc²) became a symbol of modern physics. Einstein died in 1955 in Princeton, leaving behind a significant scientific legacy.
