Yes. Jewish historians wrote about him. Here is an example.
Flavius Josephus, in his Jewish Antiquities (XVIII, 64 [iii, 3]), mentions certain events in the life of Jesus, adding: “And the tribe of the Christians, so called after him, has still to this day [about 93*C.E.] not disappeared.” Pliny the Younger, governor of Bithynia in 111 or 112*C.E., faced with the ‘Christian problem,’ wrote to Emperor Trajan, outlining the methods he was using and asking for advice. “I have asked them in person if they are Christians,” wrote Pliny. If they admitted it, they were punished. However, others “denied that they were or ever had been Christians.” Put to the test, not only did these offer up pagan sacrifices but they even “reviled the name of Christ: none of which things, I understand, any genuine Christian can be induced to do.” In answering this letter, Trajan commended Pliny on the way he had handled the matter: “You have followed the right course of procedure .*.*. in your examination of the cases of persons charged with being Christians.”—The Letters of Pliny, X, XCVI, 3,*5; XCVII, 1.
These historians were Jewish and did not like Jesus or his followers called Christians. But they wrote about him and that proves that he did exist.
