Yes, mathematicians entirely built the raw mathematical tools that made General Relativity (GR) possible, but
Albert Einstein was the one who gave those tools physical meaning.
Einstein did not invent the mathematics of curved spacetime. When he realised that gravity was a consequence of curved geometry, he lacked the advanced mathematical vocabulary required to prove it. He had to rely heavily on existing mathematical frameworks and collaborate directly with contemporary mathematicians to finalise the theory.
The Mathematicians Behind the Framework
Einstein standing on the shoulders of giants applies directly to the mathematical architecture of GR:

Bernhard Riemann (Riemannian Geometry): In 1854, Riemann developed the mathematics of multi-dimensional curved spaces (manifolds). At the time, it was treated as pure, abstract geometry with no expected applications to the physical world.

Gregorio Ricci-Curbastro &
Tullio Levi-Civita (Tensor Calculus): Around 1900, these Italian mathematicians developed "absolute differential calculus" (now known as tensor calculus). Tensors are the exact mathematical language needed to write laws of physics that remain true regardless of the coordinate system used.
Einstein's Mathematical Shield: Marcel Grossmann
In 1912, stuck and frustrated, Einstein famously wrote to his mathematician friend
Marcel Grossmann:
"Grossmann, you must help me, or else I'll go crazy!"
Grossmann went to the library, researched the latest geometry, and introduced Einstein to Riemann's and Ricci's works. Together, they published an early, foundational outline of GR in 1913.
The Race with David Hilbert
By 1915, Einstein was struggling to finalise the exact field equations for gravity. He visited the University of Göttingen and lectured on his ideas. In the audience was
David Hilbert, arguably the greatest mathematician of that era.
Recognising the brilliance of Einstein's physical ideas, Hilbert entered a friendly but intense race to find the final equations.
Hilbert actually derived the core equations using an elegant mathematical method (the principle of least action) around the exact same time Einstein reached them through grueling physical intuition.
Fixing Energy Laws: Emmy Noether
Shortly after the theory was published, physicists noticed a massive mathematical flaw: GR appeared to violate the conservation of energy. Hilbert recruited the legendary mathematician
Emmy Noether to solve it. She proved Noether's Theorem, a fundamental cornerstone of modern physics which mathematically proved how symmetries (like the universe behaving the same way yesterday as it does today) guarantee conservation laws.
Why is it "Einstein's" Theory?
Despite the immense mathematical contributions of others, Hilbert himself famously remarked that any boy in the streets of Göttingen understood the geometry better than Einstein, yet it was Einstein who did the work.
Mathematicians built the sandbox, but Einstein understood what the sand represented. He alone possessed the physical insight to map abstract geometric concepts to real-world variables:
- He equated the abstract metric tensor guv to the physical gravitational potential.
- He equated curvature to mass, momentum, and energy Tuv
- He realized that the math was describing a dynamic, physical universe where space could warp, stretch, and ripple.
Without mathematicians, Einstein would have lacked the tools to build GR. Without Einstein, the math would have remained an abstract curiosity locked in geometry textbooks.
