JEDLÍK, Štefan Anián
* 11. 1. 1800, Zemné near Komárno, Slovakia
† 12. 12. 1895, Győr, Hungary
Physicist, inventor (dynamo)
After completion of the secondary grammar school studies in Trnava and Bratislava, he entered the Benedictine order in 1817. He studied theology in Pannohalma and Rab and later mathematics and physics at the University of Budapest until 1822.
In 1828 J. constructed the moving magnet-electric motor, which was the forerunner of later electric motor that he used as a teaching tool. The invention, unfortunately, remained unnoticed even after he in 1856 reported about it at the meeting of the German Natural scientists and Physicians in Vienna. Since 1831, employed at the royal academy of Sciences in Bratislava, he continued with experiments in the field of electrical induction. From 1840 until 1878 he held a post of Professor of the University of Budapest.
He constructed a prototype of the magnetic pin, which later became a principal component of the electric locomotive. In 1858 J. discovered the dynamo principle. The unipolar dynamo constructed by him was original and simple. However, he did not dispute over the primacy of the prototype between Siemens and Wheatstone. J. also wrote a textbook but only its first part was published (Chemistry and Mechanics, 1850).
From 1858 on J. was a member of the Hungarian Academy of Sciences and obtained the title of Royal Adviser in 1867.
