The key figures in the development of the theory of relativity are Albert Einstein, who formulated both the special and general theories of relativity, and Hermann Minkowski, whose four-dimensional spacetime concept provided a geometric framework for understanding relativity. Einstein published his special theory of relativity in 1905, which revolutionized our understanding of space and time, and later, in 1915, he published the general theory of relativity, which describes gravity as a curvature of spacetime.<|im_end|>
