Perhaps his grandfather or other kind of direct relative was Rubinus, a successful soldier of Ladislaus IV of Hungary, who also elevated to the position of Judge royal in the 1280s.

[2] According to Simon Kézai's Gesta Hunnorum et Hungarorum, the ancestor of the Hermán kindred, knight Herman originated from Nuremberg, who escorted Gisela of Bavaria to Hungary in 996.

[7] Lampert's lands laid in Temes County, belonging to the local nobility surrounding the provisional royal centre Temesvár (present-day Timișoara, Romania), as historian Ildikó Tóth considered.

[10] In contrast, Iván Bertényi, Sr. argued John Csák and Lampert Hermán simultaneously held the dignity for a time until 1315, similarly to that case, where many oligarchs were styled themselves palatines during the era of feudal anarchy.

Voivode Nicholas Pok and Palatine Dominic Rátót were also appointed to their dignities at the royal court in the same period, replacing the late Ladislaus Kán and James Borsa, respectively.

He argued Lampert was also appointed as ispán of Csanád County, when the Kán clan gradually lost its influence in Transylvania since the death of their paterfamilias in early 1315.

His whole reign coincided with Charles' war against the oligarchs, when the king restored royal power primarily with the assistance of the prelates and lesser noblemen in most regions of the kingdom.

Under such conditions, when the king extended his influence gradually over the dominions one after another, Lampert had initially limited powers, practically served as judge of the royal household, instead of the whole kingdom.

[15] Initially, the authority of the institution was limited; most of his early charters contain absence or disobedience of litigants, lot of deferrals and the poor execution of the denials, which definitely reflect the faltering of judicial system, which operated with low efficiency under the conditions of the constant war situation.

[17] On Lampert's instruction, the chapters of Várad (today Oradea, Romania) and Eger functioned as the most important places of authentication for his tribunal seat.

[19] Based on the documents, Lampert performed extensive and versatile judicial activities, proving the existence of first reform steps within the dignity of Judge royal, which will be fulfilled under his successors, Alexander Köcski and Paul Nagymartoni.

[20] Among others, Lampert summoned witnesses, issued iudicialis, imposed payment of fines, registered new landowners to their newly acquired estates, confirmed royal charters in the name of the king, and sentenced in land property and criminal cases.

In 1349, the nobles of Kalonda (today part of Corund, Romania) complained in the generalis congregatio in Temes County, summoned by Palatine Nicholas Zsámboki, that their lands once were unlawfully occupied and confiscated by Lampert Hermán.

[21] Following the death of Matthew Csák in March 1321, the royal army invaded the deceased lord's province, which soon disintegrated because most of his former castellans yielded without resistance.

[25] As the Kán sons still meant a serious threat to the royal power through their continuous looting and raids, enjoying support from Basarab I of Wallachia, Charles launched a campaign to Transylvania in the summer of 1324.

On 10 July, stationing near the river of Küküllő (Târnava), Charles mentioned that his Judge royal made his last will and testament in his deathbed, while suspended and annulled fines for his spiritual salvation.
