"He was an obstinate, impetuous and rather vain little person with reddish hair; enormously wealthy, endlessly touchy, extremely intelligent and vastly attractive … he liked America, he understood it and enjoyed it; he was tremendously popular at Philadelphia, and at Washington when he condescended to appear there; he was on intimate terms at the President's House.
He was son of the diplomat Carlos Martínez de Irujo y Erice, 1st Marquis of Casa Irujo, and his wife Sarah MacKean, daughter of the Pennsylvania governor Thomas McKean.
Sarah's son, Carlos Martínez de Irujo, 2nd Marquis of Casa Irujo, would later become Prime Minister of Spain.
