applied for a letters patent for his invention on stoneprints; which
has been granted.
Jaroslav
Henevkovsky, Prague-Bubenec

of "relative colours" for transparent oil painting for which he
received a Czechoslovakian patent.

of Nikola Tesla on the
rotative magnetic field and polyphase electric current.
Antonin

shorthand-system "Simpligrafie".
Francis
Hanaman, Zagreb
->

(with Dr. Just in 1906) and was the first to propose nitration of
steel (1915).
Victor

officially recognized as being the best in the world: an electrical

Mihajlo
Pupin, New York City
->
At the age of 15 he emigrated to America where he worked in a
factory, attending evening school. He is a world-wide famous
inventor- his most important inventions are the so-called "Pupin
bobbins", which are built into Telephone Distant Lines and wires for
certain distances. They are exactly figured out mathematically by
Pupin. This invention, for which he obtained letter-patents in 1899,
made the distant-telephone possible. The value of the invention lies in the fact
that through selfinduction of the bobbins the usable effects of the
capacity of telephone lines, through which words are mutilated, are
done away with. By the introduction of electro tubes for intensity
plants it was possible by distance cables with Pupin bobbins to
obtain clear and distinct telephone intercourse at a distance of many
thousands of kilometers. There have been erected in Europe during the
last ten years in almost every country extended telephone wire nets
with Pupin plants representing an immense improvement. His inventions
are also of great influence for the development of radiotechnic.
Carl
Zipernowsky, Budapest
->
Together with the engineers Max Déri and O.T. Bláthy he
