Introduction of ankle-level amputation
Professor James Syme, one of Europe's leading surgeons of his day, was Professor of Clinical Surgery at the University of Edinburgh from 1833 to 1869. He is known for the introduction of ankle-level amputation named after him (including amputations and the speed with which their operations were carried out). -
Sewing machine
Elías Howe invented the basic concept of the sewing machine, although the mechanism was moved by a manual crank. This Massachusetts man started out as an apprentice in a machine shop and came up with an important combination of elements for the first closed-stitch sewing machine. But instead of making and selling machines, Howe made his fortune by filing lawsuits against his competitors who he claimed had infringed on his patents. -
The Invention of the telephone
Antonio Meucci built the first telephone, in order to connect his office with his bedroom (in which it was located on the second floor, due to his wife's rheumatism), having discovered that only a direct current could be used to transmit human voice .
He lacked sufficient resources to patent his invention, so he presented it to a company (they did not pay attention, but did not return the materials). Which time later Alezander Graham Bell obtained. -
Introduction of surgical antisepsis
Joseph Lister; is known for the introduction of surgical antisepsis with carbolic acid. After working as a surgeon, he observed that closed fractures rarely became infected, while open fractures produced pus, for which he deduced that some element contained in the air was responsible for the production of the infection. To prevent the proliferation of bacteria in the tissues, he applied carbolic acid on the wound, obtaining a reduction in infections. -
Pasteurization method
Some of Louis Pasteur's contemporaries; they insisted that fermentation was a chemical process and did not require the intervention of any organism. Using a microscope, Pasteur discovered that two organisms (two varieties of yeast) were involved.
Therefore, it led to pasteurization (a procedure that consists of subjecting a food to a temperature of 80 degrees in order to destroy microorganisms without altering the composition and qualities of the liquid.) -
The Phonograph
Thomas Alva Edison, made the invention of his first phonograph in 1878;
Whose phonograph uses an analog mechanical recording system in which sound waves are transformed into mechanical vibrations by means of an acoustic-mechanical transducer. These vibrations move a stylus that carves a helical groove on a phonograph cylinder. To play the sound, the process is reversed. -
Coca-Cola
The invention of coca-cola comes from the fact that at first they wanted to find a cure for headaches and stress, Pemberton experimented with the cola nut and coca. The drink, which combined lime, cinnamon, coca leaves, and Brazilian bush seeds, was called by some "the medical elixir." -
The invention of the airplane
Clément Ader; French engineer and inventor who owes it, among other inventions such as a microphone and first perfections of the telephone. He is famous especially for being the inventor of the airplane.
This comes from the fact that as a young man he was interested in the flight of birds, in addition, also in telecommunications.
In October 1890, the aircraft carried out a test on a 200-meter runway located near Paris. Piloted by Ader and with the sole presence of his employees. -
Cinematographer
Its invention comes from the lumière brothers at the end of the 19th century. On December 28, 1895, the first public exhibition of the lumière cinematograph took place in the Indian salon of the grand café, at 14 boulevard des Capuchins in paris. The program consisted of ten films of 15 to 20 meters each with a total duration of 20 minutes. These films were made by louis lumière and performed by his family and friends. -
Penicillin
On September 15, 1928, the British scientist Alexander Fleming announced the discovery of penicillin (and opened the era of antibiotics) allowing its use in the treatment of septic complications associated with fractures and other musculoskeletal injuries. Penicillin was one of the first antibiotics to be invented and also one of the most widely used worldwide. -
Titanium alloy for implants
Ronald Lawrie Huckstep designed the first interlocked nail in 1967 and the first uncemented hip prosthesis in 1979. He pioneered the use of titanium alloy for implants in 1972. The latter has been developed with the aim of obtaining better mechanical properties and minimize elements that can be harmful to health, such as aluminum.
