Johann Loserth, Austrian historian, was born 1 September 1846, at Fulnek in Moravia, where his ancestors had fled as refugees from Silesia in the 17th century. They were weavers. Since machinery encroached upon their industry, his father opened a cereal business, the proceeds of which, however, did not cover the expenses of long illness in the family. Under such circumstances there could be no thought of university training for the six sons.
Johann was then to learn cabinet making. A kindly relative made it possible for him to attend the gymnasium in Troppau and Kremsier. Because of inadequate support these were years of bitter privation. By private teaching he earned the necessary money for study. In the autumn of 1866 he went to the University of Vienna. The professors to whom he owed most were Ottokar Lorenz and Theodor Sickel; the latter admitted him in 1869 into the Institute for Research in Austrian History. After the completion of his study he taught at a Realgymnasium in Vienna. He received his doctor's degree at Tübingen (1871), and later also in Vienna (1874) for his work on the sources for the history of Kremsmünster. This publication led to a scholarly dispute with the famed historian Georg Waitz, which ended in victory for Loserth.
In 1875 Loserth was called as professor to the newly founded University of Czernowitz in Bukowina. In 1893 he was called to the University of Graz, Austria, and in 1917 he retired. In 1896 he became a member of the Academy of Vienna. He continued his writing with studies on the sources of Königsaal history, which led him into research on Cosmas of Prague and other old Bohemian sources. In this connection he published a series of critical works on the older history of Bohemia. His studies on the spiritual roots of Hussite doctrine were determinative. As a fruit of this research he published the book Huss und Wiclif (1884, second edition 1925), which proves the complete independence of the Hussite doctrines from Wycliffe's writings. These studies brought Loserth into contact with the Wycliffe Society, which began the publication of Wycliffe's Latin works in 1883. Of the 40 volumes which were published by 1922, 14, all of them first editions, were edited by Loserth. These publications are all accompanied by many critical individual inquiries, most of which were published in the writings of the Vienna Academy.
Studies in Moravian archives directed Loserth's attention to the Anabaptists, who had spread over Nikolsburg, southern Moravia, and Austria, and had carried on a live correspondence with their brethren in neighboring countries. These studies brought Loserth into connections with Joseph von Beck, whose literary legacy he took over and completed with additional archival work. Works on the history of Anabaptism in Moravia, Lower Austria, Styria, Salzburg, Tyrol, and Switzerland followed; and also a biography of Balthasar Hubmaier, and biographical sketches of Georg Blaurock, Pilgram Marpeck, and others. At an advanced age Loserth published other important works on the history of the Anabaptist movement. Among them was Pilgram Marbeck's Verantwortung (1929), a book replying to Schwenckfeld.
What Loserth discovered on the history of Anabaptism in Styria was also significant. It was shown that there were not only isolated Anabaptists there, as had previously been supposed, but that until 1530 the country was literally flooded with them. This information we owe to Dingauer, a Jesuit who was an official and father confessor in the Dietrichstein family and wrote a history of the house of Dietrichstein. He used the archives of Sigmund von Dietrichstein, who was for his part not a severe opponent of the Anabaptists, but incurred the reproach of Ferdinand for his lenience.
Finally Loserth uncovered a very valuable source on the decline of the Anabaptists in Moravia and Hungary and their restoration by the Carinthian emigrants, who were expelled to Transylvania in 1755, there became acquainted with the last remnants of the Hutterites, and finally accepted their teaching. Since they could not remain in Transylvania, they migrated to Wallachia and then to Russia; in the middle of the 19th century they went to North America (see Kuhr, Joseph).
Loserth's call to Graz opened further fields of study in the history of the Reformation and the Counter-Reformation in Inner Austria with sources and thorough treatment. This resulted in inspiration for other historical studies of the country, of history of the noble families, of economics, and of Austrian history in general. His familiarity with the intellectual currents of the 13th and 14th centuries qualified him to write the history of the late Middle Ages for the Handbuch der mittelalterlichen und neueren Geschichte von Below-Meinecke.
Loserth died in Graz on 30 August 1936, two days before the completion of his ninetieth year.
