Luther Macon Epps (January 16, 1920 – August 30, 2012), known as L. Macon Epps was an American engineer, inventor, author and poet.
 He studied Aeronautical Engineering at North Carolina State University, graduating in 1940.
 As an engineer and manager he worked for the Grumman Aerospace Corporation for 37 years.
 Most notably he worked on the Apollo Lunar Module as the Assistant Program Manager, but he also had other positions.
 As an inventor he received a patent in 1978 for a "combined water heater and sauna room heater device".
 He was a lifelong member of the Rotary International.
 After his retirement, Epps founded the I-Cubed Corporation, which specialized in new innovations and part-time jobs for other retired engineers.
 Just a few days before his death, he ended second place in a writing contest in the retirement community University Village Thousand Oaks.
Francis Melvin Rogallo (January 27, 1912 – September 1, 2009) was an American aeronautical engineer inventor born in Sanger, California, U.S.; he is credited with the invention of the Rogallo wing, or "flexible wing", a precursor to the modern hang glider and paraglider.
 His patents were ranged over mechanical utility patents and ornamental design patents for wing controls, airfoils, target kite, flexible wing, and advanced configurations for flexible wing vehicles.
Richard J. Mammone (born 1953, New York) is an American engineer, inventor, entrepreneur and professor.
 Dr. Mammone is a serial entrepreneur who enjoys forming and managing new ventures, applying expertise and vision to bring innovations to the marketplace.
 As an inventor, he holds over 15 patents. To date, he has formed four technology companies including SpeakEZ, a firm that specialized in voice recognition technology, and Computed Anatomy Inc., the business that pioneered LASIK eye surgery.
Mark Rober (born 11 March 1980) is an American engineer, inventor and YouTube personality.
 He is best known for his YouTube videos on popular science, do-it-yourself gadgets and creative ideas.
 His most popular invention is Digital Dudz, a range of Halloween costumes that integrate mobile apps with clothing.
 As an engineer, Rober spent seven years working on the Curiosity rover at NASA's Jet Propulsion Laboratory.
Coleman Sellers II (January 28, 1827 – December 28, 1907) was a prominent American engineer, chief engineer of William Sellers & Co. professor of mechanics at the Franklin Institute, professor of engineering practice at Stevens Institute of Technology and inventor.
 He obtained more than thirty letters-patent for inventions of his own, and served as presidents of the American Society of Mechanical Engineers in the year 1886-87.
Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an American engineer and inventor, and an early computer and Internet pioneer.
 He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, and the development of hypertext, networked computers, and precursors to graphical user interfaces.
 These were demonstrated at The Mother of All Demos in 1968.
 Engelbart's Law, the observation that the intrinsic rate of human performance is exponential, is named after him.
In human–computer interaction, an organic user interface (OUI) is defined as a user interface with a non-flat display.
 After Engelbart and Sutherland's graphical user interface (GUI), which was based on the cathode ray tube (CRT), and Kay and Weiser's ubiquitous computing, which is based on the flat panel liquid-crystal display (LCD), OUI represents the third wave of display interaction paradigms, pertaining to multi-shaped and flexible displays.
 In an OUI, the display surface is always the locus of interaction, and may actively or passively change shape upon analog (i.e., as close to non-quantized as possible) inputs.
 These inputs are provided through direct physical gestures, rather than through indirect point-and-click control.
 Note that the term "Organic" in OUI was derived from organic architecture, referring to the adoption of natural form to design a better fit with human ecology.
 The term also alludes to the use of organic electronics for this purpose.
Jack David Fischer (born January 23, 1974) is an American engineer, test pilot and a NASA astronaut.
 Fischer was selected in June 2009 as a member of the NASA Astronaut Group 20 and qualified as an astronaut in 2011.
 He made his first spaceflight in April 2017, as a flight engineer for Expedition 51/52 on the International Space Station.
William Seward Burroughs I (January 28, 1855 – September 15, 1898) was an American inventor born in Rochester, New York.
Gary Keith Starkweather (born January 9, 1938) is an American engineer and inventor most notable for the invention of the laser printer and color management.
