February 17 – Happy Birthday, Jozef Murgas

Posted on February 17, 2016

If someone's called a “Renaissance Man,” he's probably had a lot of occupations, or he's made contributions to several different fields.

Today's famous birthday is a Renaissance Man: an inventor, an architect, a painter, a biologist, and a priest. Since he helped develop wireless telegraphy and other wireless communications, I think we could fudge that “inventor” label towards him being a physicist and engineer, don't you?

Jozef Murgas was born in Tajov, which at the time was in the Kingdom of Hungary, which in turn was part of the Austrian Empire. But Tajov is no longer part of Hungary OR Austria; it's in Slovakia!

Slovakia is in the middle of this map and is
colored a dark brown-red.

During his student days, Murgas was noted for his work in physics and in art. But he was also learning theology (the study of religion), and soon he was ordained as a Roman Catholic priest.

While working as a priest, Murgas studied painting in Budapest (Hungary) and Munich (Germany). But after eight years, Murgas emigrated to the U.S. There he worked as a priest but started to work in electrotechnology, publishing papers, obtaining patents, and starting a company.

Along with all this work on wireless communication, Murgas took care of Slovak immigrants. He founded a community organization that took care of children and youths. He published a newspaper. He had a new library, cemetery, gymnasium, and several schools and playgrounds built. He organized a charity, took political action, wrote articles, and supported the creation of the nation of Czechoslovakia (which has since ceased to exist).

Murgas financed some of this cool stuff by selling paintings he painted.

He continued to do experiments in physics, and he also collected mushrooms, plants, minerals, and insects. His butterfly collection included 9,000 butterflies from all over the world.

I think the main contribution that Murgas made was to make all of the rest of us feel like lazy slugs!




In Pennsylvania, in King's College, there is a museum
exhibit of Murgas's paintings and other works.

May 30, 2013 - Loomis Day

Loomis was a dentist.
Today we are encouraged to celebrate Mahlon Loomis for “thinking outside of the box.” He came up with the idea of wireless communication—a telegraph that would harness the electrical currents in the Earth's upper atmosphere to transfer telegraph messages without the need for wires.

Loomis did not come up with a working idea of how to do this! His patent application not only had no schematic diagram about how to build a wireless telegraph, nor any theoretical backing for his concept, it was also very close to the idea and even wording of a patent application already awarded to William Henry Ward. Both patents applications were vague and impractical.

Loomis did do an experiment that seemed to demonstrate the first wireless communication in the world. He flew two kites at equal heights 14 miles away from one another; each kite was tied to a copper string, and each string was attached to a galvanometer. Loomis was able to use one kite to move the other kite's meter!
This is NOT what was happening during
the experiment!

Loomis thought that, because the two kites were flown at the same height, he was creating a closed circuit as electricity moved from a transmitter, up a wire, through a particular layer of atmosphere, and down the other wire to the meter. However, scientists now know that the atmosphere creating one leg of a closed circuit is impossible. Instead, scientists speculate, Loomis was unknowingly creating a radio signal with one apparatus, and the equal-length wire of the other kite was resonant with that signal and therefore acted as a radio receiver. Interesting, huh?

What would we do without
wireless technology today?
Loomis received his patent on this date in 1872. I personally find value in people thinking up all sorts of outlandish possibilities—artists and science fiction writers are two groups of people who often make these sorts of contributions to society—but I admire even more the scientists who work hard to discover principles of the universe and engineers who work hard to create devices that work. Loomis didn't succeed at either of these – but he did indeed think outside of the box!
