The middle part of the nineteenth century is a period which has become more or less obscure to most Americans and Englishmen. At one end the thunderous campaigns of Napoleon are dying away. In the latter part of the century we remember the gorgeousness of the Tuileries, the four years' strife of our own Civil War, and then the golden drift of peace with which the century ended. Between these two extremes there is a stretch of history which seems to lack interest for the average student of to-day.

In America, that was a period when we took little interest in the movement of affairs on the continent of Europe. It would not be easy, for instance, to imagine an American of 1840 cogitating on problems of socialism, or trying to invent some new form of arbeiterverein. General Choke was still swindling English emigrants. The Young Columbian was still darting out from behind a table to declare how thoroughly he defied the British lion. But neither of these patriots, any more than their English compeers, was seriously disturbed about the interests of the rest of the world. The Englishman was contentedly singing "God Save the Queen!" The American, was apostrophizing the bird of freedom with the floridity of rhetoric that reached its climax in the "Pogram Defiance." What the Dutchies and Frenchies were doing was little more to an Englishman than to an American.

Continental Europe was a mystery to English-speaking people. Those who traveled abroad took their own servants with them, spoke only English, and went through the whole European maze with absolute indifference. To them the socialist, who had scarcely received a name, was an imaginary being. If he existed, he was only a sort of offspring of the Napoleonic wars—a creature who had not yet fitted into the ordinary course of things. He was an anomaly, a person who howled in beer-houses, and who would presently be regulated, either by the statesmen or by the police.

When our old friend, Mark Tapley, was making with his master a homeward voyage to Britain, what did he know or even care about the politics of France, or Germany, or Austria, or Russia? Not the slightest, you may be sure. Mark and his master represented the complete indifference of the Englishman or American—not necessarily a well-bred indifference, but an indifference that was insular on the one hand and republican on the other. If either of them had heard of a gentleman who pillaged an unmarried lady's luggage in order to secure a valuable paper for another lady, who was married, they would both have looked severely at this abnormal person, and the American would doubtless have added a remark which had something to do with the matchless purity of Columbia's daughters.

If, again, they had been told that Ferdinand Lassalle had joined in the great movement initiated by Karl Marx, it is absolutely certain that neither the Englishman nor the American could have given you the slightest notion as to who these individuals were. Thrones might be tottering all over Europe; the red flag might wave in a score of cities—what would all this signify, so long as Britannia ruled the waves, while Columbia's feathered emblem shrieked defiance three thousand miles away?

And yet few more momentous events have happened in a century than the union which led one man to give his eloquence to the social cause, and the other to suffer for that cause until his death. Marx had the higher thought, but his disciple Lassalle had the more attractive way of presenting it. It is odd that Marx, today, should lie in a squalid cemetery, while the whole western world echoes with his praises, and that Lassalle—brilliant, clear-sighted, and remarkable for his penetrating genius—should have lived in luxury, but should now know nothing but oblivion, even among those who shouted at his eloquence and ran beside him in the glory of his triumph.

Ferdinand Lassalle was a native of Breslau, the son of a wealthy Jewish silk-merchant. Heymann Lassal—for thus the father spelled his name—stroked his hands at young Ferdinand's cleverness, but he meant it to be a commercial cleverness. He gave the boy a thorough education at the University of Breslau, and later at Berlin. He was an affectionate parent, and at the same time tyrannical to a degree.

It was the old story where the father wishes to direct every step that his son takes, and where the son, bursting out into youthful manhood, feels that he has the right to freedom. The father thinks how he has toiled for the son; the son thinks that if this toil were given for love, it should not be turned into a fetter and restraint. Young Lassalle, instead of becoming a clever silk-merchant, insisted on a university career, where he studied earnestly, and was admitted to the most cultured circles.

Though his birth was Jewish, he encountered little prejudice against his race. Napoleon had changed the old anti-Semitic feeling of fifty years before to a liberalism that was just beginning to be strongly felt in Germany, as it had already been in France. This was true in general, but especially true of Lassalle, whose features were not of a Semitic type, who made friends with every one, and who was a favorite in many salons. His portraits make him seem a high-bred and high-spirited Prussian, with an intellectual and clean-cut forehead; a face that has a sense of humor, and yet one capable of swift and cogent thought.

No man of ordinary talents could have won the admiration of so many compeers. It is not likely that such a keen and cynical observer as Heinrich Heine would have written as he did concerning Lassalle, had not the latter been a brilliant and magnetic youth. Heine wrote to Varnhagen von Ense, the German historian:
