He was a Polish Jew who spoke several languages, including German. He served as George Washington's spy among the British forces by becoming a translator for the British in passing orders to their Hessian troops. Zealous as a saboteur (He was caught helping French and American prisoners to escape and persuading Hessians to defect), he was apprehended and imprisoned by the British. He escaped, "leaving behind his wife and a one month old baby and belongings worth about five thousand pounds."13 Solomon returned to finance and rebuilt a fortune while putting his talents and the proceeds of his successful ventures at the disposal of members of the Continental Congress and of the Revolution.
