The date of his birth is uncertain. In addition to the year 1667, the dates October 28, 1687, and 1678 also appear. Questions also arise regarding his nationality; some sources list him as Austrian, while others list him as Hungarian. His father is described as a banker in Vienna, but he completed his studies in Hungarian schools. He entered the order in either 1705 or 1715.
In addition to his priestly duties, he practiced medicine, both in Hungary and later in South America. He arrived in Argentina around 1717 and played a significant role in combating the plague epidemics of 1719 and 1730. When the Jesuits were expelled in 1767, he was permitted to remain on the continent primarily because of his medical work. He is not listed in the historical register of Hungarian Jesuits.
