Ányos Jedlik (Hungarian "Jedlik István Ányos";
Slovak"Štefan Anián Jedlík") ( January 11, 1800– December 13, 1895) was a Hungarian inventor, engineer, physicist, Roman Catholic priest, member of the Hungarian Academy of Sciences, and author of several books in Hungarian. He is considered to be the Unsung Father of the Dynamo.
He was born in the in Szimő today Zemné, in the
Komárom countyof the Kingdom of Hungary, Austrian Empire(now Slovakia). He was Hungarian [cite web|title=Hungarian Cultural Contributions|publisher="Lél F.

Jedlik's education began at high schools in Nagyszombat, today Trnava and Pozsony, today Bratislava. In 1817 he became a Benedictine and from that time continued his studies at the schools of that order. He lectured at
Benedictineschools up to 1839, then for 40 years at the " Budapest Universityof Sciences" department of physics-mechanics. Only few guessed at that time that his beneficial activities would play an important part in bringing up a new generation of physicists.
In 1845 he began teaching his pupils in Hungarian instead of
Latin. Through his textbook he is regarded as one of the establishers of Hungarian vocabulary in physics. He became the dean of the faculty of arts in 1848, and by 1863 he was rector of the University. From 1858 he was a corresponding member of the Hungarian Academy of Sciencesand from 1873 an honorary member. He preceded his contemporaries in his scientific work, but he did not speak about his most important invention, his prototype dynamo, until 1856; it was not until 1861 that he mentioned it in writing in a list of inventory of the university. Although that document might serve as a proof of Jedlik's status as the originator, the invention of the dynamo is linked to Siemens' name because Jedlik's invention did not rise to notice at that time.
In 1827, he started experimenting with electromagnetic rotating devices which he called "lightning-magnetic self-rotor". In the prototype both the stationary and the revolving parts were electromagnetic. In 1873 at the
World's Fairin Viennahe demonstrated his lighting conductor.
After his retirement he continued working and spent his last years in complete seclusion at the priory in
Győr, the Kingdom of Hungary, Austria-Hungary where he died.
Ányos Jedlik's best known invention is the principle of 'self-excitement'. With the single pole electric starter, he formulated the concept of the
dynamoat least 6 years prior to Siemens and Wheatstone. In essence the concept is that instead of permanent magnets, two electromagnetsopposite each other induce the magnetic fieldaround the rotor.
As one side of the coil passes in front of the north pole, crossing the line of force, current is thus induced. As the frame rotates further the current diminishes, then arriving at the front of the south pole it rises again but flows in the opposite direction. The frame is connected to a
commutator, thus the current always flows in the same direction in the external circuit.
