A former personal assistant to a top executive at Goldman Sachs jumped to his death from a Manhattan hotel on Tuesday, the same day he was scheduled to appear in federal court on a criminal charge related to a lucrative theft from his former boss, the authorities said.

The former assistant, Nicolas De-Meyer, was accused of stealing more than $1.2 million in high-end wine from the collection of his former boss, David M. Solomon, who is now the chief executive of Goldman Sachs.

Mr. De-Meyer was scheduled to appear in federal court at 2:30 p.m. on Tuesday, court records show. The police responded to a call about a person who jumped from a hotel at 2:38 p.m.

Mr. De-Meyer, 41, jumped from the 33rd floor of the Carlyle, a luxury hotel on the Upper East Side where he had been staying, the police said. The authorities said he was pronounced dead at the scene.
