Table Telegraph built by Maximiliano Herrmann and innovated later by Cristiano Augusto Bramão. This is an innovative piece in the world of communication since it allowed a faster transmission and reception as well as a better economy in the consumption of the ticker tape, due to its double chain operation. With this innovation, Herrmann intended to fix the problem in the Telegraphic Morse Receivers. Before there was a major technical problem since the Morse Receivers were constituted with a dry tip or a strip with ink. In the dry tip case, the signals were marked in the paper with a steel pointer, but these were of difficult perception and disappeared easily. With the ink on paper strip method it was, sometimes, impossible to read due to the excess of ink. Because of these technical problems, Herrmann built a type of inkstand with a thin stylus, flexible enough to allowed the user to adjust, using just the enough amount of ink to write the message. This innovation was made known to the Foreign Telegraphic Administrations and was presented in 1865 at the International Telegraphic Conference in Paris, by José Vitorino Damásio, director of the Portuguese Telegraphs. This rectangular trapezoidal shaped piece is made of wood, golden brass, metal and glass. The front face has a plate on which the model is identified. In the right side of the upper panel there is a reel with paper tape where the telegraphic message was printed, also containing two morse keys that worked with a manual computer. In the center and in the left there is a clockwork mechanism consisting of a mechanical system of gears in brass, copper and metal. At the rear face there is six pins for connecting wires identified by the letters

Maximiliano Augusto Herrmann (1838-1930): Pioneer of Portuguese Telecommunications

Maximiliano Augusto Herrmann stands as a pivotal figure in the history of Portuguese engineering and innovation, largely unrecognized outside specialist circles until recent decades. Born in Lisbon on April 17, 1838, he possessed an inquisitive mind and a relentless dedication to advancing technological capabilities – qualities that would propel him to become one of Portugal’s foremost inventors and engineers.

Early Life & Education: Herrmann’s formative years were marked by a fervent pursuit of knowledge. He commenced his formal education at the Industrial Institute of Lisbon (1857-1862), diligently absorbing the principles of mechanics and instrumentation. This academic grounding served as an indispensable foundation for his subsequent inventive endeavors, shaping his understanding of scientific methodology and fostering a lifelong fascination with technological progress.

The Herrmann Wall Telephone – A Revolutionary Breakthrough: Herrmann’s most enduring legacy resides in his groundbreaking creation of the “Herrmann wall telephone,” introduced in 1880. Recognizing the cumbersome nature of existing telephone systems—characterized by complex wiring and laborious operation—he conceived a radical design prioritizing simplicity and accessibility. His ingenious innovation incorporated buttons to activate the instrument, dramatically reducing operational effort and facilitating the rapid expansion of public telephone lines throughout Portugal’s major urban centers. The meticulous construction of the telephone demanded precision; double earpieces crafted from flexible tubes ensured optimal sound transmission, complemented by a fixed transmitter embodying Herrmann’s unwavering commitment to detail.

Campaign Telegraph – Enhancing Morse Code Transmission: Expanding his expertise beyond telephony, Herrmann confronted the challenges inherent in telegraphic communication. He spearheaded significant improvements to Morse receivers by streamlining their design and simplifying regulation—a contribution lauded at the International Telegraphic Conference held in 1865. These advancements underscored Herrmann’s dedication to maximizing efficiency and broadening access to this burgeoning field of communication, reflecting his belief that technological innovation should serve the betterment of society.

International Recognition & Awards: Herrmann’s inventive prowess garnered considerable acclaim internationally. He received numerous accolades for his contributions to engineering, solidifying his reputation as a visionary thinker and innovator. His unwavering commitment to scientific exploration propelled him to become a respected figure within Portugal's intellectual landscape.

The “Campaign Telegraph,” another testament to Herrmann’s ingenuity, utilized Morse code transmission with transmitter and receiver components—a pivotal step forward in enhancing telegraphic performance. These innovations underscored his understanding of fundamental principles of electrical signaling and cemented his place as a cornerstone of Portuguese technological history.

Herrmann's influence extended beyond individual inventions; he actively championed advancements in telegraph technology and fostered collaboration within the scientific community. His dedication to improving communication infrastructure undeniably shaped Portugal’s technological landscape during the late 19th century, leaving an indelible mark on the nation’s progress.
