As a boy of twelve Hauser made an extensive and successful concert tour.  In 1840 he toured Europe, and ten years later went to London, and thence to the West Indies and the United States, where he made quite a sensation, and was a member of Jenny Lind’s company.  He afterwards visited San Francisco, where he got himself into difficulties on account of Lola Montes.  Then he went to South America, visiting Lima, where passionate creoles languished for him, Santiago, where a set of fanatics excited the mob against him, declaring that he was charmed by the devil, and Valparaiso, where he suffered shipwreck.

He then proceeded to the Sandwich Islands, where he played before the royal family and all the dusky nobles.  They listened solemnly, but made no sign of approbation, and Hauser felt that he was sinking into a mere nothing in their esteem.  In desperation he tore the strings from his violin and played, with all his power, several sentimental songs on the G string only.  Then he gave them Paganini’s witches’ dance.  This succeeded, and they gave a yell of joy and wanted more.  They particularly delighted in harmonic effects, and before long were willing to do anything for the foreigner who could pipe on the wood as well as any bird.  He became a hero at Otaheite, but was obliged to continue on his journey.  He next visited Australia, and while in Sydney he made such a success that he was presented with the freedom of the city and thanked by the government for his playing.

In 1860 he reached Turkey, where he played before the Sultan, who beat time to his music and seemed highly delighted.  Hauser had many amusing stories to tell of his travels, and especially of his experiences in the Sandwich Islands and Turkey, Cairo and Alexandria.  His adventures, which were numerous and thrilling, were published in two volumes, in Vienna.

Hauser was not the possessor of a great technique, but there was something characteristic and charming in his tone and mannerisms, which were especially pleasing to the fair sex.  He was a man of restless, and, in some respects, dissatisfied nature.  Some of his compositions are still to be found on concert programmes, and these he used to play exquisitely.  Hauser lived in retirement in Vienna after concluding his travels, and in 1887 he died practically forgotten.

Few violinists succeeded more completely in captivating their audiences than Henri Wieniawski, whose impetuous Slavonic temperament, with its warm and tender feeling, gave a colour to his playing, which placed his hearers entirely under his control, went straight to their hearts, and enlisted their sympathy from the very first note.  Both fingering and bowing were examples of the highest degree of excellence in violin technique, and difficulties did not exist for him.  At times his fiery temperament may have led him to exaggeration, and to a step beyond the bounds of good taste, but this was lost sight of in the peculiar charm of his playing, its gracefulness and piquancy.
