Meanwhile, Girard, realizing the opportunities which the new Republic promised, had become a citizen, taking the oath of allegiance at Philadelphia on the twenty-seventh of October, 1778. Among the first of the millions of old-world people who in the years which followed were destined to renounce the oppressive institutions of their native lands and become naturalized citizens of the free United States, it is particularly interesting that Girard was born in a country which likewise was soon to cast aside the rule of kings and establish the institutions of a republic.

From now on Girard’s fortune seemed steadily to advance. In 1789 George Washington became the first President of the new Republic. With the cessation of war at home and abroad, commerce was again resumed, and an era of prosperity gave to such men as Stephen Girard the opportunity to reap richly of the world’s commercial harvest.

Crop failures in France had created a demand for foreign wheat, and to stimulate its importation the French Government offered a premium to anyone importing it. It was an attractive speculation, and Girard, with his eye ever scanning world opportunities while others passed them by, saw his chance to turn an honest penny. Promptly his own ships and other chartered vessels were filled with grain, and an abundant profit was quickly realized.

In these early days, the yellow fever, now eradicated by modern knowledge of sanitation, took each year its death-toll among the inhabitants of southern countries, and from time to time extended far beyond its normal field. Girard, and, in fact, most of the American merchants of that day, had conducted a large business with San Domingo, the principal trading centre of the West Indies. In 1791, however, the large negro population of the island revolted, and fire, slaughter, and plunder soon turned the prosperous community into a wilderness. White refugees crowded every outgoing vessel and by the hundreds began to pour into Philadelphia and other American seaboard cities. “Take advantage of my brig Polly,” wrote Girard to a friend on the unhappy island, “if she still be in the harbor, to come here and enjoy the peace which our Republican Government, founded as it is on the rights of man, assures to all its inhabitants.”

But with the refugees came also the dreaded plague, and baffling the skill of the doctors, it spread through Philadelphia until the streets were crowded with funerals and the church-bells seemed continually to toll. There were few hospitals in those days, and the Philadelphia hospital at Bush Hill was not only crowded far beyond its capacity, but was in wretched condition, owing to the lack of attendants. Girard was put on a committee, and that very evening reported the immediate need of nurses and money. But Girard did not stop with his duties as committeeman. Without hesitation, and totally ignoring the probability of contracting the fever himself, he and a fellow townsman, Peter Helm, assumed active control of the hospital, and day and night, throughout the plague, toiled at this self-imposed work of mercy among the sick and the dying.

Among the various accounts of the plague the following is of particular interest in its mention of Girard: “Stephen Girard, a French merchant long resident here, and Peter Helm, born here of German parents, men whose names and services should never be forgotten, had the humanity and courage constantly to attend the hospital, and not only saw that the nurses did their duties, but they actually performed many of the most dangerous, and at the same time humiliating services for the sick with their own hands.”

When the plague was over, Girard returned to his business. In February, 1793, France declared war on Great Britain, and immediately British troops and ships seized the French cities in San Domingo. Ships of war and privateers of both countries promptly swarmed over the seas. Decrees were soon published by the nations at war, forbidding neutral vessels to trade with enemy ports. The law of nations was disregarded, and American ships were seized and confiscated. Great Britain particularly ignored the rights of American ship-owners, and thousands of dollars worth of American ships and cargoes were soon in British hands. Two of Girard’s ships, the Kitty and the Sally, were taken. Commerce was demoralized.

In retaliation against the outrages perpetrated by the British and the French, a “non-intercourse bill” provided that after November 1, 1794, “all commercial intercourse between the citizens of the United States and the subjects of the King of Great Britain should cease.” The bill was lost in the Senate, but an embargo which closed all American ports to foreign trade accomplished practically the same end. In all, five ships belonging to Girard were now in enemy hands.

In October, 1801, after eight years of war, peace was concluded between France and Great Britain, and in December the war which the United States had been conducting against France was also ended. With the return of peace came renewed commercial activity. Girard at once availed himself of the opportunity, and soon his ships were engaged in trade with the ports of France and Russia. But this revival of commerce was of short duration, for the unsettled state of Europe soon resulted in new blockades of ports, embargoes, and acts of non-intercourse against the offending countries. Then, to complete the disaster, in 1810 Napoleon annexed Holland to France and issued a decree “by which American ships and cargoes, seized in the ports of Holland, Spain, France, and Naples, to the value of ten million dollars, were condemned and sold.” Five of Girard’s ships which had sailed for northern ports were now seized and held by the Danes, and it was many months before their release could be secured. Trade with Europe was at an end; but despite the heavy losses which Girard had suffered, he did not hesitate or allow himself to be mastered by the situation. If Europe was closed, South America and the Far East were open to him, and now his ships began new commerce with new continents, and in December, 1810, the ship Montesquieu set sail for Valparaiso and Canton.

During these years of commercial activity Girard had become a large investor in real estate, and of his profits from his trading ventures at sea he had in 1812 almost four hundred thousand dollars invested in farm acres and lots and buildings in Philadelphia. In 1812 the United States declared war against Great Britain. Bad feeling had long existed, due primarily to the disregard of the British for the rights of American vessels. For a long time Great Britain persisted in stopping our ships, taking American seamen out of them and forcing them to serve on British vessels. It was more than patriotism could bear, and the nation enthusiastically entered the war with the cry of “Free Trade and Sailor’s Rights.” Forced practically from the sea, Girard turned his great abilities to finance and the service of his country.
