Dan Oster, age 15, of Great Falls, Mont., for his question:

WHO WAS ROGER SHERMAN?

Roger Sherman was the only man who signed ail four of these great documents: the Articles of Association in 1774, the Declaration of Independence in 1776, the Articles of Confederation in 1777 and the United States Constitution in 1789.

He was influential in the Continental Congress where John Adams said he was "as firm in the cause of American Independence as Mount Atlas."

Sherman served as judge of the Connecticut Superior Court from 1766 to 1789. Although he was born in Massachusetts, he moved to Connecticut when he was 22 and became prominent in business and politics.

Sherman feared excesses when the revolutionary movement began, but he was among the first to deny the supremacy of the British Parliament over the colonies.

During the Constitutional Convention of 1787, Sherman presented the Connecticut Compromise that resolved the differences between the large and small states on representation in the national legislature.

Sherman served his state in the United States Congress as representative from 1789 to 1791 and as a senator from 1791 to 1793.
