Jozef Murgaš

Jozef Murgaš

Jozef Murgaš (English Joseph Murgas) (17 February 1864 – 11 May 1929) was a Slovak inventor, architect, botanist, painter, and Roman Catholic priest. He contributed to wireless telegraphy and help develop mobile communications and wireless transmission of information and human voice.

Murgaš was nicknamed the Radio Priest and deemed a Renaissance man.

Life

Europe

Murgaš was born in Tajov (Tajó), Kingdom of Hungary, Austrian Empire (now Slovakia). He studied theology in Prešporok (Pressburg, present Bratislava) (1880–82), Esztergom (1882–84), and in Banská Bystrica, where he graduated in 1888. From his youth he was bright, skillful and good at painting and electrotechnology: The vice-head of the school in Esztergom allowed him to use the physics room for experiments, and the Slovak painters B. Klemens and Dominik Skutecký noticed his talent for painting.

After priestly St. George, which is still on the church altar of the village. The central altar painting of St. Elisabeth, in the 14th century Church of St. Elizabeth in the main square of Banská Bystrica, is by Murgaš.

United States

Due to permanent conflicts with the bishop's secretary, Murgaš had to emigrate to the Saints Cyril and Methodius community and took care of children and youth. He was very popular among religious people because of his emotional relation to them. He also published a newspaper, in which he published some popular-science articles and verses.

Murgaš was active in the Slovak expatriates movement, wrote articles for their press, was one of the founders of the Slovak League in America, actively supported the creation of the state of Pittsburgh Agreement (1918) between Czechs and Slovaks on establishing Czechoslovakia. As a respected personality, he gained trust and support of the highest authorities in the USA for the establishment of Czechoslovakia.

Murgaš continued to study physics and to do many experiments. He financed his activities by selling his paintings. He also collected mushrooms, plants, minerals and insects. His butterfly collection comprised 9000 pieces from all over the world.

When the United States entered World War I, private radiotelegraphy stations were prohibited, which put an end to Murgaš's pioneer work in this field. After the creation of Czechoslovakia, he returned to Slovakia in 1920, where he taught electrotechnology at a high school, but since he did not find appropriate understanding by the Ministry of Education in Prague, he returned to Wilkes-Barre four months later. He was nominated to be a member of the Federal Radio Commission of the United States in 1925. Murgaš died in Wilkes-Barre four years later.

Importance and primacy conflicts

The most dynamic segments in the area of communications services today are internet services, mobile telephony and convergence of voice and data process. If we go back one hundred years to history we can see that development in this area began with wireless information transmission encoded in telegraphy marks and wireless voice transmission which was made by frequency modulation.

In 1905, Murgaš achieved radio transmission between Wilkes-Barre and Scranton, Pennsylvania, or a distance of 20 miles (30 km).

The tone system is the use of two signals of different frequencies, i.e. Murgaš substituted the "dot" of the Morse code with a higher tone and the "dash" with a lower tone (this is the 1904 patent "The way of transmitted messages by wireless telegraphy").

Thomas Edison paid remarkable attention to Murgaš's experiments and he is said to have informed G. Marconi of Murgaš's success. Murgaš's lab in Wilkes-Barre was visited by President Theodore Roosevelt in 1905.

Memorials and honors

In Tajov, there is Murgaš's house where he was born, a memorial room, and a symbolic grave with a sepulchral monument of Murgaš at the local cemetery. Jozef Šebo, the founder of the room and monument (now a retired teacher) looks after them very carefully. The memorial room also features originals of pictures, paintings, some unique pieces from his butterfly collection, models of inventions in wireless telegraphy and documents. One can also see there a minimodel of Murgaš's original antenna masts built by company Universal Aether Telegraph Co. in Wilkes-Barre in 1905.

Further objects include:

  • Jozef Murgaš Monument in Bratislava, Slovakia – the Slovak Telecom building in the Jarošova Street
  • Jozef Murgaš street in Podbrezová-Lopej, Slovakia
