At least since the 20th century I haven't been able to find an exception. Even GMs who did not get their GM titles until late in life were very strong players as children. For example Ben Finegold did not get his last norm to become GM until he was 40, but he was a USCF master at age 14. All the other stories I've seen are similar. I've also yet been unable to find more than two or three people who started playing seriously after age 25 and ever broke 2000 FIDE.
