I'd heard of the revenue cutter before, but not the man it was named after. He also played a role in the Civil War as it turns out.
From Wikipedia.
CALEB CUSHING (January 17, 1800 to January 2, 1879)
Was an American Democratic politician and diplomat who served in Congress from Massachusetts and was attorney general under President Franklin Pierce. He was an eager proponent of American territorial and commercial expansion, especially regarding the acquisition of Texas, Oregon and Cuba.
He believed that enlarging the American sphere of influence would would fulfill "the great destiny reserved for this exemplar American Republic."
He also secured a treaty with China in 1844, which opened five ports to American trade.. After the Civil War, he secured a treaty with Colombia to give the United States a right-of-way for a transoceanic across the isthmus of Panama.
In addition, he also helped obtain a favorable settlement of the Alabama Claims, and as the ambassador to Spain in the 1870s, helped defuse the troublesome Virginius Affair.
