Wilhelm Emil Fein (16 January 1842 – 6 October 1898) was a German inventor. He invented the worldwide first portable electric drill.

Jan Paweł Nowacki (25 June 1905, in Berlin – 23 May 1979, in Warsaw) was an engineer. He worked for the British during World War II on radar installations, and later had a career as a university lecturer.

Robert M. Haralick (born 1943) is Distinguished Professor in Computer Science at Graduate Center of the City University of New York (CUNY). Haralick is one of the leading figures in computer vision, pattern recognition, and image analysis. He is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) and a Fellow and past president of the International Association for Pattern Recognition.
Professor Haralick is the King-Sun Fu Prize winner of 2016, "for contributions in image analysis, including remote sensing, texture analysis, mathematical morphology, consistent labeling, and system performance evaluation".

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.

Robert Haig Weitbrecht (1920-1983) was an engineer at SRI International and later the spin-off company Weitbrecht Communications who invented a type of a modem (a form of acoustic coupler).

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.
