Gagern was the son of a former minister of the Grand Duke of Nassau, who had left that State to take service in Austria, and who had acted with the Archduke John in planning a popular rising in the Tyrol in 1813. Heinrich had been trained at a military school in Munich. He had steadily opposed the policy of Metternich, had done his best to induce the universities to co-operate in a common German movement, and had tried to secure internal liberties for Hesse-Darmstadt, while he had urged his countrymen to look for the model of a free constitution rather to England and Hungary than to France. During the constitutional movement of 1848 he had become Prime Minister of Hesse-Darmstadt; and he seems to have had considerable power of winning popular confidence. Although he was not able to commit the meeting to a definitely monarchical policy, he had influence enough to counteract the attempts of Struve and Hecker to carry a proposal for the proclamation of a republic; and his influence increased during the later phases of the movement.

It was obvious that, in the state of Viennese feeling, a movement in favor of German unity, at once so determined and so moderate in its character, would give new impulse to the hopes for freedom already excited by Kossuth's speech; and the action of the reformers now became more vigorous because the students rather than the professors were guiding the movement. Some of the latter, and particularly Professor Hye, were beginning to be alarmed, and were attempting to hold their pupils in check. This roused the distrust and suspicion of the students; and it was with great difficulty that Professors Hye and Endlicher could prevail on the younger leaders of the movement to abstain from action until the professors had laid before the Emperor the desire of the university for the removal of Metternich. This deputation waited on the Emperor on March 12th, but it proved of little avail; and when the professors returned with the answer that the Emperor would consider their wishes, the students received them with laughter and resolved to take the matter into their own hands. The next day was to be the opening of the Assembly of the Estates of Lower Austria; and the students of Vienna resolved to march from the University to the Landhaus.

In the great hall of the University, now hidden away in an obscure part of Vienna but still retaining traces of the paintings which then decorated it, the students gathered in large numbers on March 13th. Various rumors of a discouraging kind had been circulated; this and that leading citizen were mentioned as having been arrested; nay, it was even said that members of the Estates had themselves been seized, and that the sitting of the Assembly would not be allowed to take place. To these rumors were added the warnings of the professors.

Fuester, who had recently preached on the duty of devotion to the cause of the country, now endeavored, by praises of the Emperor, to check the desire of the students for immediate action; but he was shouted down.

Hye then appealed to them to wait a few days, in hopes of a further answer from the Emperor. They answered with a shout that they would not wait an hour; and then they raised the cry of "Landhaus!" Breaking loose from all further restraint they set out on their march, and as they went numbers gathered round them. The people of Vienna had already been appealed to, by a placard on St. Stephen's Church, to free the good Emperor Ferdinand from his enemies; and the placard further declared that he who wished for the rise of Austria must wish for the fall of the present ministers of state.

The appeal produced its effect; and the crowd grew dense as the students marched into the narrow Herren Gasse. They passed under the archway which led into the courtyard of the Landhaus; there, in front of the very building where the Assembly was sitting, they came to a dead halt; and, with the strange hesitation which sometimes comes over crowds, no man seemed to know what was next to be done. Suddenly in the pause which followed, the words "Meine Herren" were heard from a corner of the crowd. It was evident that some one was trying to address them; and the students nearest to the speaker hoisted him upon their shoulders. Then the crowd saw a quiet-looking man, with a round, strong head, short-cropped hair, and a thick beard. Each man eagerly asked his neighbor who this could be; and, as the speech proceeded, the news went round that this was Doctor Fischhof, a man who had been very little known beyond medical circles and hitherto looked upon as quite outside political movements. Such was the speaker who now uttered what is still remembered as the "first free word" in Vienna.

He began by dwelling on the importance of the day and on the need of "encouraging the men who sit there," pointing to the Landhaus, "by our appeal to them, of strengthening them by our adherence, and leading them to the desired end by our coöperation in action. He," exclaimed Fischhof, "who has no courage on such a day as this is only fit for the nursery." He then proceeded to dwell at some length on the need for freedom of the press and trial by jury. Then, catching, as it were, the note of Kossuth's speech of March 3d, he went on to speak of the greatness which Austria might attain by combining together "the idealist Germans, the steady, industrious, and persevering Slavs, the knightly and enthusiastic Magyars, the clever and sharp-sighted Italians." Finally he called upon them to demand freedom of the press, freedom of religion, freedom of teaching and learning, a responsible ministry, representation of the people, arming of the people, and connection with Germany.

In the mean time the Estates were sitting within. They had gathered in unusually large numbers, being persuaded by their President that they were bound to resist the stream of opinion. Representatives as they were of the privileged classes, they had little sympathy with the movement that was going on in Vienna. Nor does it appear that there was anyone among them who was disposed to play the part of a Confalonieri or Szechenyi, much less of a Mirabeau or a Lafayette. Many of them had heard rumors of the coming deputation; but Montecuccoli, their President, refused to begin the proceedings before the regular hour. While they were still debating this point they heard the rush of the crowd outside; then the sudden silence, and then Fischhof's voice. Several members were seized with a panic and desired to adjourn. Again Montecuccoli refused to yield, and one of their Liberal members urged them to take courage from the fact of this deputation to make stronger demands on the Government.

But before the Assembly could decide to act the crowd outside had taken sterner measures. The speakers who immediately followed Fischhof had made little impression; then another doctor, named Goldmark, sprang up and urged the people to break into the Landhaus. So, before the leaders of the Estates had decided what action to take, the doors were suddenly burst open, and Fischhof entered at the head of the crowd. He announced that he had come to encourage the Estates in their deliberations, and to ask them to sanction the demands embodied in the petition of the people. Montecuccoli assured the deputation that the Emperor had already promised to summon the Provincial Assemblies to Vienna, and that, for their part, the Estates of Lower Austria were in favor of progress. "But," he added, "they must have room and opportunity to deliberate." Fischhof assented to this suggestion, and persuaded his followers to withdraw to the courtyard. But those who had remained behind had been seized with a fear of treachery, and a cry arose that Fischhof had been arrested. Thereupon Fischhof showed himself, with Montecuccoli, on the balcony; and the President promised that the Estates would send a deputation of their own to the Emperor to express to him the wishes of the people. He therefore invited the crowd to choose twelve men, to be present at the deliberations of the Estates during the drawing up of the petition. While the election of these twelve was still going on, a Hungarian student appeared with the German translation of Kossuth's speech. The Hungarian's voice being too weak to make itself heard, he handed the speech to a Tyrolese student, who read it to the crowd. The allusion to the need of a constitution was received with loud applause, and so also was the expression of the hopes for good from the Archduke Francis Joseph.

But however much the reading of the speech had encouraged the hopes of the crowd, it had also given time for the Estates to decide on a course without waiting for the twelve representatives of the people; and, before the crowd had heard the end of Kossuth's speech the reading was interrupted by a message from the Estates announcing the contents of their proposed petition. The petition had shrunk to the meagre demand that a report on the condition of the state bank should be laid before the Estates, and that a committee should be chosen from Provincial Assemblies to consider timely reforms and to take a share in legislation.
