Samuel Dioszegi was born in Debrecen on 29 or 30 December 1760. After completing seminary and theology, he traveled to Göttingen as a traveling student, where he studied engineering, natural sciences and medicine at the university. Here he became acquainted with Carl von Linnaeus' system of classification of the natural sciences, which he later used in his works, and he was probably the first scholar to write in the Hungarian language.
After returning to Hungary, he was a priest in Hajdonanas and Hajdoboszormeny, and then in Debrecen. He married the sister of his friend, the poet and botanist Mihaly Fazekas. Together with the author Ludas Matyi, they wrote the Hungarian Herbal Book. Six years later, in 1813, Dioszegi wrote and self-published Herbal Medicine. He was one of the great scholar-priests of his day, of whom his co-pastor, Joseph Foldvari, wrote: “Being a great lover of science, there was no part or branch of it from which he did not acquire knowledge. He needed, both from his teachings in the living language and from his sermons In print, in all his other works traces of his broad scope and lofty ideas are evident.His sermons were characterized by the use of natural images, which made the oral messages more comprehensible to the audience.
