I was researching the unified field theory timeline and found that Schrodinger also spent years on the same problem. Both men working in parallel on the same dead end is a striking detail.
The last major project Einstein worked on before his death in 1955 was a Unified Field Theory, an attempt to combine gravity and electromagnetism into a single mathematical framework. He spent roughly the last 30 years of his life on it. He never succeeded, and most physicists at the time considered the effort misguided. The problem he was trying to solve, unifying all fundamental forces, remains unsolved.
