American electrical engineers

Ronald Ellwin Evans Jr. (November 10, 1933 – April 7, 1990) was an American electrical engineer, aeronautical engineer, officer and aviator in the United States Navy, and NASA astronaut. As Command Module Pilot on Apollo 17 he was one of the 24 astronauts to fly to the Moon, and one of 12 people to fly to the Moon without landing.
Before becoming an astronaut, Evans graduated with a Bachelor of Science degree in electrical engineering from the University of Kansas and joined the U.S. Navy in 1956. After receiving his naval aviator wings, he served as a fighter pilot and flew combat missions during the Vietnam War. In 1964 he received a Master of Science degree in aeronautical engineering from the U.S. Naval Postgraduate School. Achieving the rank of captain, he retired from the Navy in 1976.
Evans was selected as an astronaut by NASA as part of NASA Astronaut Group 5 in 1966 and made his only spaceflight as command Module pilot aboard Apollo 17 in December 1972, the last crewed mission to the Moon, with Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt. During the flight, Evans and five mice orbited the Moon a record 75 times as his two crewmates descended to and explored the surface. He is the last person to orbit the Moon alone and, at 147 hours and 43 minutes, holds the record for the most time spent in lunar orbit. During Apollo 17's return flight to Earth, Evans performed an extravehicular activity (EVA) to retrieve film cassettes from the service module. It was the third "deep space" EVA, and is the spacewalk performed at the greatest distance from any planetary body. As of 2024, it remains one of only three deep space EVAs, all made during the Apollo program's J-missions. It was the final spacewalk of the Apollo program.
In 1975, Evans served as backup Command Module Pilot for the Apollo–Soyuz Test Project mission. He worked on the development of the Space Shuttle before retiring from NASA in March 1977 to become a coal industry executive.

Robert J. Weber (1942 in Stout, Iowa – 21 November 2018 in Des Moines) was an American engineer and researcher who specialized in microwave engineering, device fabrication, fiber optics, and sensor design. He was professor emeritus of Iowa State University‘s Department of Electrical and Computer Engineering and a life fellow of the Institute of Electrical and Electronics Engineers (IEEE).Weber received his Ph.D. from Iowa State in 1967. He worked for Rockwell Collins for 25 years before becoming a professor in 1988. He retired in 2010.

Jack Justin Stiffler (1934–2019) was an American electrical engineer, computer scientist and entrepreneur, a Fellow of the Institute of Electrical and Electronics Engineers who made key contributions in the areas of communications (especially coding theory) and fault-tolerant computing.

Kitty O'Brien Joyner (July 11, 1916 – August 16, 1993) was an American electrical engineer with the National Advisory Committee for Aeronautics (NACA), and then with the National Aeronautics and Space Administration (NASA) upon its replacement of NACA in 1958. She was the first woman to graduate from the University of Virginia's engineering program in 1939, receiving the Algernon Sydney Sullivan Award upon graduation. When she was hired by NACA the same year, she became the first woman engineer at the organization, eventually rising to the title of Branch Head and managing several of its wind tunnels. Her work contributed to research on aeronautics, supersonic flight, airfoils, and aircraft design standards.

John Peter Costas (1923 in Wabash, Indiana – August 9, 2008) was an American electrical engineer. Costas invented, among other things, the Costas loop and Costas arrays.

Lawrence Joseph Giacoletto (November 14, 1916, in Clinton, Indiana – October 4, 2004, in Okemos, Michigan) was an American electrical engineer and inventor. He was known among others for his work in the field of semiconductor circuit technology, in particular by the eponymous Giacoletto equivalent circuit for transistors (also known as Hybrid-pi model).

Bernard Valentine Vonderschmitt (October 14, 1923 – June 9, 2004) was an electrical engineer, most noted as a co-founder of leading FPGA producer Xilinx.

Charles Sidney Burrus (October 9, 1934 in Abilene, Texas - April 3, 2021) was an American electrical engineer and the Maxfield and Oshman Professor Emeritus of Electrical and Computer Engineering at Rice University in Houston, Texas. He is widely known for his contributions to digital signal processing, especially FFT algorithms, IIR filter design, and wavelets.

Benjamin Franklin "Tex" Logan, Jr. (June 6, 1927 – April 24, 2015) was an American electrical engineer and bluegrass music fiddler.
Born in Coahoma, Texas, Logan earned a B.Sc. in electrical engineering at Texas Tech University, then Texas Technological College, in Lubbock, Texas, studied for a B.Sc. in engineering at Massachusetts Institute of Technology (1946–51), and completed a M.Sc. (1956). He then moved to New Jersey where he joined Bell Labs (1956) and started his doctoral studies at Columbia University. There he earned a Ph.D. in electrical engineering with his dissertation "Properties of High-Pass Signals" (1965). Logan joined the communication theory department at Bell Labs (1956) where he and others demonstrated the use of computer simulation in the study of reverberation in digital audio, and did joint work with Manfred R. Schroeder who later pioneered MP3 audio (1961). He was with the mathematics center (1963–93) where he contributed to the theory of signals.
As was his father Frank, Logan was a fiddler. He played with Mike Seeger in the late 1950s, with The Lilly Brothers & Don Stover and Bill Monroe in the 1960s, and with Peter Rowan in the 1980s. He performed on several records and international tours, and had minor roles in movies as well. Logan wrote "Christmas Time's A-Coming", a song made popular by Bill Monroe that has been recorded by many performers, including Johnny Cash, Emmylou Harris, Sammy Kershaw, Rhonda Vincent, and Patty Loveless, among others; and "Diamond Joe" recorded by Bob Dylan. In 1969, Logan played fiddle on the Bee Gees' 1969 song "Give Your Best", released on the band's sixth album Odessa.
Logan died April 24, 2015, in Morristown, New Jersey, by the side of his daughter, Jody.

Heinrich Göbel, or Henry Goebel (April 20, 1818 – December 4, 1893) was a German-born American precision mechanic and inventor. In 1848 he immigrated to New York City, where he resided until his death. He received American citizenship in 1865.
In 1893, magazines and newspapers reported 25 years earlier, Göbel had developed incandescent light bulbs comparable to those invented in 1879 by Thomas Alva Edison. Göbel did not apply for a patent.
In 1893, the Edison Electric Light Company sued three manufacturers of incandescent lamps for infringing Edison's patent. The defense of these companies claimed the Edison patent was void because of the same invention by Göbel 25 years earlier, which came to be known as the "Göbel defense".
Judges of four courts raised doubts; there was no clear and convincing proof for the claimed invention. A research work published in 2007 concluded that the Goebel-Defense was fraudulent.After Göbel's death, in some countries, the legend arose he was the true inventor of the practical incandescent light bulb.
Göbel acquired patents for an improvement of sewing machines (1865), for an improvement of the Geissler pump (1882) and for a technique to connect carbon threads to metal wires in incandescent lamps (1882). These three patents had no influence on further technical developments.
