After completion of the secondary school studies in Trnava and Bratislava, he has entered into the Benedictian order. He studied theology in the church seminar in Pannohalma and concurrently, he studied mathematics and physics at the Faculty of Philosophy of the University of Budapest, where he obtained the degree Doctor of Philosophy. In the period 1821 - 1829 he has acted as the professor of physics at the Benedictinian grammar school in Györ. From 1829 until 1840 he has acted as the professor of physics at the royal academy of sciences in Bratislava. From 1848 until 1878 he was appointed as the Professor and from 1863 he was appointed as Dean of the University of Budapest.

In 1859 - 61 he constructed a prototype of the unipolar dynamo - his most outstanding invention. Among his other inventions there are a new type of capacitor, a tube lightning collector, the optical grating cutter, and he conducted valuable research studies in the area of physics and optics as well as the experimental and pedagogical work.
