Ferdinand Braun Biography

Among his groundbreaking achievements were the creation of the cathode-ray tube, which became the foundation for television and computer displays, as well as the development of wireless technology to cover considerable spaces. Braun took lessons in math and chemistry in the University of Marburg before switching to physics in the University of Berlin, where he earned his doctorate in March 1872 having a dissertation on the oscillations of elastic strings. Later, Braun was employed as a graduate assistant at Wrzburg University. Braun’s first groundbreaking work came along with his research of the features of electrolytes and crystals that conduct electricity. In 1874, Braun identified the rectification effect in the idea of contact between metals and specific crystal substances using a semiconductor device—a discovery that helped bring about the creation of the radio a few decades later.

Braun accepted a set of teaching places while he continued his scientific experiments. Braun moved on to similar places at Strasbourg University in 1880, after which in the Polytechnic school in Karlsruhe in 1883, during which time he wed Amelie Bhler. In 1897, the physicist invented the cathode-ray tube, also called the Braun tube. By utilizing magnetic forces in a vacuum tube to deflect cathode rays, Braun could create a fluorescent picture on a display. The cathode-ray tube would end up being the main electronic display device for radar, tv and computers before the close of the 20th century, when flat screen technologies were introduced.

Braun shortly became interested in wireless technology. Italian inventor Guglielmo Marconi had conducted the very first successful wireless transmission in 1895, but the antenna was right in the ability circuit and broadcast medium was restricted in range. Braun solved this issue by creating a sparkless antenna circuit that linked transmitter capacity to the antenna circuit inductively, significantly raising the broadcast medium range of a transmitter.

This discovery enabled Marconi to run the very first transatlantic transmission in 1901, and finally resulted in the creation of the wireless technology sector. In 1914, Braun was summoned to the Big Apple as a witness in a suit regarding a patent claim of the American Marconi Company from the Atlantic Communication Company. However , the escalation of World War I kept him from leaving New York in the decision of the suit and returning to his lab in Germany. Braun spent his remaining years at among his son’s houses in Brooklyn, ny, where he expired on April 20, 1918.
