Albert Einstein

Albert Einstein (1879–1955) was a theoretical physicist widely regarded as one of the most influential scientists of the twentieth century. Born in Ulm, Germany, he developed the theory of relativity, fundamentally changing the human understanding of space, time, and gravity. His most famous equation, E = mc², revealed the relationship between mass and energy. In 1921, he was awarded the Nobel Prize in Physics for his explanation of the photoelectric effect, which helped establish quantum theory. Beyond his scientific work, Einstein was a committed advocate for peace, civil rights and humanitarian causes.
