Elihu Brintnal Frost (May 12, 1860 – August 22, 1925) was an American lawyer[1] with an early involvement in the submarine industry.
While at Yale, Frost was a member of the student secret society Skull and Bones.
[2] In 1893 the United States Congress funded a $200,000 prize for submarine construction, and Frost lent John Philip Holland the funds he needed to participate in this prize contest.
[3] When Isaac Rice formed the Electric Boat Company (the predecessor of General Dynamics) to build Holland's submarine designs, Frost became the company's vice-president, secretary, and chief financial officer.
[4][5][6][7][8][9] When he died of paresis in Beach Bluff, Massachusetts,[2] he left his estate to a female friend (later determined to be his fiancée), cutting off his relatives.
