A telefon-hirmondó ismertetése (The introduction of the Telephone announcer)
Budapest: Markovits, 1897? First edition. In original paper. 48 p. Mint conditon.
On February 15, 1893, the world's first telephone announcer spoke from the studio at 6 Magyar utca in Budapest's 5th district.
The essence of the invention was to distribute a speaker's voice, multiplying it, between listening devices of their choice. The broadcasting studio and the Budapest network were soon established, which was independent of the already existing telephone lines and devices. This is how the "Telephone Announcer" appeared for the first time in the world (1893), the immediate predecessor of radio.
Tivadar Puskás (1844–1893) was decisive in the life of the 1876 World's Fair in Philadelphia, where Alexander Graham Bell presented his new invention, the telephone. From there, Puskás' path led to the great genius of the era, Thomas Alva Edison, in whose laboratory he worked for almost a year in Menlo Park. He played an important role in the establishment of the Boston telephone exchange, and then, on behalf of Edison, he also supervised the construction of the London and Paris exchanges. Most historians of science dispute the decisive role of Puskás in the development of the operating principle of the telephone exchange, saying that there is no trace of this in The Edison Papers archive, and no such reference was found in the correspondence between Edison and Puskás. At the same time, it is a fact that in 1911, during his trip to Hungary, Edison gave Puskás' sister-in-law a dedicated portrait in which he called the Hungarian inventor the first in the world to "invent the idea of the telephone exchange"
One of the the earliest publication about "Telephone announcer", the immediate predecessor of radio.
