Elias Boudinot Caldwell (April 3, 1776 – May 30, 1825) was a Clerk of the Supreme Court of the United States. Born in Elizabethtown, New Jersey, Caldwell was two-years-old when his mother, Hannah, was killed by British troops passing through their farm. A short time later in 1781 Reverend James Caldwell, his father, was murdered and Caldwell was adopted by Elias Boudinot, for whom he was named. Caldwell graduated from the College of New Jersey (now Princeton University) and studied law with the said Elias Boudinot until his move to the District of Columbia.
