History of Electrical Engineering

Electricity has been a scientific concern since at least the early 17th century. William Gilbert was a pioneering electrical scientist who was the first to distinguish between magnetism and static electricity. The name “electricity” is attributed to him. He also created the sensorium, which detects the presence of statically charged things. In 1762, Swedish scholar Johan Wilcke devised the electrophorus, a device that produced a static electric charge. Alessandro Volta invented the voltaic pile, the precursor of the electric battery, by 1800.

The 19th century marked significant advancements in electricity and telegraphy. Notable developments included the discoveries of Hans Christian Ørsted, who found that electric current produces a magnetic field, and Michael Faraday, who made breakthroughs in electromagnetic induction. James Clerk Maxwell’s unified theory of electricity and magnetism further propelled the field. The era also witnessed the establishment of electrical engineering departments and degree programs, such as the first one at Technische Universität Darmstadt in 1882.

During this time, telegraphy played a crucial role in communication. Innovations like the electrostatic telegraph by Georges-Louis Le Sage and the electrolyte telegraph system proposed by Francisco Salva Campillo set the stage for electrical engineering as a profession. Additionally, the introduction of standardized units of measure at the international conference in Chicago in 1893 paved the way for future advancements and standardization efforts in various industries.

Practical applications of electricity expanded rapidly, with Thomas Edison’s large-scale electric power network and the invention of the steam turbine by Sir Charles Parsons. The development of alternating current (AC) systems, including AC motors, by Galileo Ferraris, Nikola Tesla, and others, transformed power generation. The “war of the currents” between AC and direct current (DC) systems ultimately led to the adoption of AC as the prevailing standard. The 19th century witnessed remarkable progress in electricity, telegraphy, and the establishment of electrical engineering as a discipline. These advancements revolutionized communication, and power generation, and laid the foundation for future innovations.

Numerous scientists and inventors contributed significantly to the advancement of radio technology and electronics. In the 1850s, James Clerk Maxwell’s mathematical work lay the framework for comprehending electromagnetic radiation and radio waves. By emitting and receiving radio waves, Heinrich Hertz’s tests in 1888 validated Maxwell’s theory. Guglielmo Marconi expanded on these discoveries by successfully transmitting wireless signals over increasing distances, eventually achieving transatlantic transmission in 1901.

Other developments were occurring concurrently. Jagadish Chandra Bose pioneered the use of semiconductor junctions to detect radio waves and researched millimeter wave communication. Karl Ferdinand Braun invented the cathode ray tube, which became an essential component of electronic television, and John Fleming, Robert von Lieben, and Lee De Forest made key contributions to the development of radio tubes and amplifiers.

Later, Albert Hull’s magnetron inspired the development of the microwave oven, and radar technology based on the magnetron debuted in the 1930s. The first completely functional and programmable computers, such as Konrad Zuse’s Z3 in 1941 and Tommy Flowers’ Colossus in 1943, heralded the computing era. In 1948, Claude Shannon published his mathematical theory of communication, which advanced our understanding of information transfer.

Overall, advances in radio technology and electronics laid the groundwork for modern communication systems and computing technologies.
