Ernst Julius Berg (9 Feb. 1871 - 1941) was a Swedish-born, American electrical engineer.
Ernst Julius Berg (9 Feb. 1871 - 1941) was a Swedish-born, American electrical engineer.
Ernst Julius Berg was born in Östersund, Jämtland County in Sweden. After graduating from the Royal Institute of Technology in Stockholm in 1892, he immigrated to the United States. He began working as an assistant to Charles Proteus Steinmetz at General Electric. He then joined the faculty of electrical engineering at Union College.
In 1909, he became head of electrical engineering department at the University of Illinois. Berg remained as department head until June 1913, when he resigned and returned to his former positions with General Electric Company and with Union College. He was associated with Union College until his death in 1941. A pioneer of radio, he produced the first two-way radio voice program in the United States. In the field of theoretical analysis of electrical circuits, he popularized Oliver Heaviside's technique of operational calculus.
In 1906 he married Gwendoline O'Brien. He is buried in Vale Cemetery in Schenectady, New York.
Charles Proteus Steinmetz was an American mathematician and electrical engineer and professor at Union College. He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers. He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to design better electromagnetic apparatus equipment, especially electric motors for use in industry.
Oliver Heaviside FRS was an English self-taught mathematician and physicist who invented a new technique for solving differential equations, independently developed vector calculus, and rewrote Maxwell's equations in the form commonly used today. He significantly shaped the way Maxwell's equations are understood and applied in the decades following Maxwell's death. His formulation of the telegrapher's equations became commercially important during his own lifetime, after their significance went unremarked for a long while, as few others were versed at the time in his novel methodology. Although at odds with the scientific establishment for most of his life, Heaviside changed the face of telecommunications, mathematics, and science.
The Heaviside step function, or the unit step function, usually denoted by H or θ, is a step function named after Oliver Heaviside, the value of which is zero for negative arguments and one for nonnegative arguments. It is an example of the general class of step functions, all of which can be represented as linear combinations of translations of this one.
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor therefore needs no electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type.
Arthur Edwin Kennelly was an American electrical engineer.
Vale Cemetery is a historic rural cemetery and the largest cemetery in Schenectady, New York. It opened on 21 October 1857, when the Rev. Julius Seely dedicated what was then termed "the Vale". It has tripled its size since opening and today it holds the remains of some of the most notable persons in Upstate New York. In 1973, a 35-acre tract of unused and abandoned cemetery land around the ponds of Cowhorn Creek was sold to the city of Schenectady to form Vale Park.
Ernst Frederick Werner Alexanderson was a Swedish-American electrical engineer, who was a pioneer in radio and television development. He invented the Alexanderson alternator, an early radio transmitter used between 1906 and the 1930s for longwave long distance radio transmission. Alexanderson also created the amplidyne, a direct current amplifier used during the Second World War for controlling anti-aircraft guns.
John Roy Whinnery was an American electrical engineer and educator who worked in the fields of microwave theory and laser experimentation.
Balthasar van der Pol was a Dutch physicist.
Walter Ransom Gail Baker was an American electrical engineer. He was a vice president of General Electric, and was Director of Engineering for the Radio Manufacturers Association. At the urging of James Lawrence Fly, Chairman of the Federal Communications Commission (FCC), Baker founded the National Television System Committee, or NTSC, in 1940. He served as president of the Institute of Radio Engineers (IRE) in 1947.
Operational calculus, also known as operational analysis, is a technique by which problems in analysis, in particular differential equations, are transformed into algebraic problems, usually the problem of solving a polynomial equation.
Robert E. Doherty (1885–1950) was an American electrical engineer who served as the third President of Carnegie Mellon University in Pittsburgh, Pennsylvania, United States.
The IEEE Nikola Tesla Award is a Technical Field Award given annually to an individual or team that has made an outstanding contribution to the generation or utilization of electric power. It is awarded by the Board of Directors of the IEEE. The award is named in honor of Nikola Tesla. This award may be presented to an individual or a team.
General Electric Research Laboratory was the first industrial research facility in the United States. Established in 1900, the lab was home to the early technological breakthroughs of General Electric and created a research and development environment that set the standard for industrial innovation for years to come. It developed into GE Global Research that now covers an array of technological research, ranging from healthcare to transportation systems, at multiple locations throughout the world. Its campus in Schenectady, New York was designated a National Historic Landmark in 1975.
Charles Concordia was a noted American electrical engineer specializing in electrical power engineering and the early history of computer hardware.
John Renshaw Carson was an American transmission theorist for early communications systems. He invented single-sideband modulation and developed the Carson bandwidth rule for estimating frequency modulation (FM) bandwidth. In 2013 Carson was inducted into the Electronic Design Hall of Fame for his contributions to communications.
Donald Glen Fink was an American electrical engineer, a pioneer in the development of radio navigation systems and television standards, vice president for research of Philco, president of the Institute of Radio Engineers, General Manager of the IEEE, and an editor of many important publications in electrical engineering.
The General Electric Realty Plot, often referred to locally as the GE Realty Plot, GE Plots or just The Plot, is a residential neighborhood in Schenectady, New York, United States. It is an area of approximately 90 acres (36 ha) just east of Union College.
James John Smith was an Irish applied mathematician and electrical engineer. His career was mostly spent at General Electric (GE) in Schenectady, New York.
The Charles Proteus Steinmetz Memorial Lecture is a series of academic lectures initiated in 1925 in honor of celebrated mathematician and electrical engineer Charles Proteus Steinmetz. To date seventy four addresses have been given on subjects ranging from peace and educational reform to nanotechnology and solar photovoltaics.
