"János Bánfihunyadi (Hungarian: Bánfihunyadi János; 1576 – 28 August 1646), better known by his Latinized name Johannes Banfi Hunyades[b] or his pseudonym Hans Hungar, was a Hungarian alchemist, chemist and metallurgist. He emigrated to England in 1608 and built a reputation among the academic circles of England and Hungary, associating with such figures as the alchemist Arthur Dee, astrologer William Lilly, physician Jonathan Goddard and scientist Kenelm Digby
Born in Nagybánya, Hungary in 1576, Banfi Hunyades took an apprenticeship in goldsmithing in his hometown. Between 1606 and 1608 he took a journey through Europe, passing through Germany and arriving in England by 1608. Upon his arrival he became a successful goldsmith in London, visiting Hungary several times before settling in England upon his marriage to Dorothy Colton in 1619, to whom he had 4 children. Banfi Hunyades kept up his contacts with several eminent Hungarian figures and, in 1633, he was invited by the Prince of Transylvania to occupy a position at his planned academy. As of 1633, Banfi Hunyades took a position at Gresham College, lecturing and experimenting in chemistry with several eminent scientists at the College until as late as 1642. In 1646, before a planned trip with Arthur Dee to Hungary in search of antimony, Banfi Hunyades died on 28 August." - (en.wikipedia.org 11.08.2021)
