Technology and Engineering Atlas

Open Questions

Things this atlas does not know. Each entry is a question that specialists have posed and not settled, recorded with what would actually resolve it and which expertise the answer needs.

These are kept deliberately, rather than quietly omitted. An atlas that shows only what it is sure of implies a confidence it has not earned, and the gaps are often where the interesting work is. Several sit exactly where two fields fail to meet: identifying the hyssop of the Hebrew Bible needs a botanist and a philologist of Biblical Hebrew, and neither one settles it alone.

Grouped by the part of the atlas the question sits in. Start here if you know the territory better than the technique.

Geological Engineering What year did geological engineering originate as a distinct discipline?

Open Geological Engineering

Why It Is Open Wikipedia states the term geological engineering was not coined until the 19th century and ties the field's formal creation to a run of dam failures in the 1950s and 1960s, but names no single founding year for either the term or the discipline.

What Would Settle It A history-of-engineering source naming the specific year the term geological engineering was first used, or the specific year the first dedicated university program or professional body was established.

Expertise Needed History of engineering

Question posed in Geological Engineering (Wikipedia), Wikipedia contributors, History section, term coined in the 19th century paragraph.

Civil Engineering When did civil engineering begin as a distinct discipline: with John Smeaton's 1771 self-designation, or with millennia of unnamed pre-professional practice?

Open Civil Engineering

Why It Is Open Wikipedia's own civil engineering article calls Smeaton "the first self-proclaimed civil engineer" (1771, Eddystone Lighthouse) while the same article calls the discipline "the second-oldest engineering discipline after military engineering," reaching back to Egyptian, Mesopotamian, Greek and Roman construction with no professional title attached. Historians differ on whether "civil engineering" names a practice (ancient) or a profession (18th century onward).

What Would Settle It A settled historiographical convention on whether "engineering" disciplines are dated from their professional/institutional founding or from the earliest practice they describe; no such family-wide convention exists yet.

Question posed in Civil Engineering (Wikipedia), Wikipedia contributors, History section, Smeaton and Institution of Civil Engineers founding paragraph.

Electrical Engineering Who should be credited as inventor of the integrated circuit: Jack Kilby (hybrid IC, Texas Instruments, 1958) or Robert Noyce (monolithic IC, Fairchild Semiconductor, 1959)?

Open Electrical Engineering

Why It Is Open Wikipedia's electrical engineering article states plainly that "the first integrated circuits were the hybrid integrated circuit invented by Jack Kilby...in 1958 and the monolithic integrated circuit chip invented by Robert Noyce...in 1959," naming two independent inventors and two designs rather than one. Kilby received the 2000 Nobel Prize in Physics partly for this work; Noyce, who died in 1990, could not share it. This is exactly the kind of priority dispute the technology atlas records as the field's character.

What Would Settle It Historians of technology generally treat this as a case of near-simultaneous independent invention rather than a resolvable priority question; what would resolve it is a family-wide decision on how to record dual/independent invention rather than forcing a single credited inventor.

Question posed in Electrical Engineering (Wikipedia), Wikipedia contributors, History section, integrated circuit paragraph.

Chemical Engineering When and by whom was the term "chemical engineering" actually coined: an 1839 reference cited by James F. Donnelly, George E. Davis's later claimed coinage, or the approximately 1890 date given by The History of Science in the United States: An Encyclopedia?

Open Chemical Engineering

Why It Is Open Wikipedia's own chemical engineering article records three competing accounts in one paragraph: "A 1996 article cites James F. Donnelly for mentioning an 1839 reference to chemical engineering...George E. Davis...was credited with having coined the term...The History of Science in United States: An Encyclopedia puts the use of the term around 1890." The sources disagree with each other and the article does not adjudicate between them.

What Would Settle It A dedicated etymological study tracing first use of the exact phrase "chemical engineering" in primary 19th-century sources, rather than secondary encyclopedic accounts that already disagree.

Question posed in Chemical Engineering (Wikipedia), Wikipedia contributors, Etymology section.

Software Engineering Is software engineering genuinely a form of engineering in the licensed-profession sense, and should software engineers be licensed as Professional Engineers the way civil or electrical engineers are?

Open Software Engineering

Why It Is Open Wikipedia's software engineering article records that "the NCEES began offering a Professional Engineer exam for Software Engineering in 2013...NCEES ended the exam after April 2019 due to lack of participation. Mandatory licensing is currently still largely debated, and perceived as controversial." The same article notes the ACM and IEEE Computer Society examined licensing in the 1990s and concluded it was inappropriate for industrial practice, a conclusion the article says was not universally accepted.

What Would Settle It A revival of the licensing exam with sustained participation, or a clear professional consensus statement from ACM/IEEE Computer Society settling whether licensure suits the field, neither of which exists yet.

Question posed in Software Engineering (Wikipedia), Wikipedia contributors, Profession section, NCEES licensing paragraph.

Aerospace Engineering Did Gustave Whitehead achieve powered, controlled flight near Bridgeport, Connecticut in 1901-1902, before the Wright brothers' 1903 flights at Kitty Hawk?

Open Aerospace Engineering

Why It Is Open Wikipedia's Gustave Whitehead article states "controversy surrounds published accounts and Whitehead's own claims that he flew a powered machine successfully several times in 1901 and 1902, predating the first flights by the Wright brothers in 1903." Connecticut's legislature officially recognized Whitehead as "Father of Connecticut Aviation" in 1968; North Carolina's General Assembly passed a 1985 resolution giving the claim "no credence." Mainstream aviation historians side with the Wright brothers, but the dispute remains live enough to have produced competing state resolutions decades apart.

What Would Settle It Physical evidence (a surviving aircraft, verifiable photograph, or independently corroborated eyewitness record) of a genuinely powered, controlled 1901-1902 Whitehead flight, which mainstream aviation historians say does not exist.

Question posed in Gustave Whitehead (Wikipedia), Wikipedia contributors, Lead section, controversy statement.

Computer Engineering Was the Atanasoff-Berry Computer (1939-1942) the first electronic digital computer, given that it was neither programmable nor Turing-complete?

Open Computer Engineering

Why It Is Open Wikipedia's Atanasoff-Berry Computer article states the ABC "was the first automatic electronic digital computer...The ABC's priority is debated among historians of computer technology, because it was neither programmable, nor Turing-complete." A 1973 US federal court ruling (Honeywell v. Sperry Rand) held the ENIAC patent invalid because ENIAC derived key ideas from the ABC, but that legal ruling settled a patent case, not the historians' definitional debate over what should count as the "first" electronic digital computer.

What Would Settle It A settled, family-wide definitional standard for what counts as a "computer" (mere electronic arithmetic vs. programmability vs. Turing-completeness) applied consistently across every early-computing priority claim, which does not yet exist in the historical literature.

Question posed in Atanasoff-Berry Computer (Wikipedia), Wikipedia contributors, Lead section, priority-debate sentence.

Industrial Engineering Who deserves primary credit for founding industrial engineering as a discipline: Frederick Winslow Taylor, originator of time study, or Frank and Lillian Gilbreth, originators of motion study?

Open Industrial Engineering

Why It Is Open Time study and motion study were developed independently and stood in philosophical tension; the disagreement between Taylor and the Gilbreths became a personal rift that, after Taylor died, turned into an open feud between the Gilbreths and the Taylor camp, and the documented record states that friction over questions of history and intellectual property still remains even after Lillian Gilbreth attempted to heal the rift.

What Would Settle It A settled historical account, backed by primary correspondence or patent records, establishing whose methodological contribution founded industrial engineering as a discipline and how the intellectual property dispute between the two camps was actually resolved.

Expertise Needed History of Technology

Question posed in Frank Bunker Gilbreth (Wikipedia), Wikipedia contributors, Wikipedia, Frank Bunker Gilbreth, section Scientific management.

Nuclear Engineering Who deserves primary credit for founding nuclear engineering: Leo Szilard, who conceived and patented the chain reaction concept in 1933 and 1936, or Enrico Fermi, who led the team that achieved the first actual self sustaining chain reaction in 1942?

Open Nuclear Engineering

Why It Is Open Szilard originated and patented the theoretical concept of a nuclear chain reaction years before any working device existed, while Fermi led the team that turned the concept into the first working reactor at Chicago Pile One in 1942 and later jointly held a nuclear reactor patent together with Szilard; historical accounts differ on which contribution defines the founding of the discipline, and Fermi has separately been called the architect of the nuclear age.

What Would Settle It A settled historiographical consensus, or a definitive patent and priority record, on whether conceptual origination or first successful engineering achievement carries primary founding credit.

Expertise Needed History of Technology

Question posed in Leo Szilard (Wikipedia), Wikipedia contributors, Wikipedia, Leo Szilard, lead section.

Robotics Engineering Who actually coined the word robot: Karel Čapek, who used it in his 1920 play R.U.R., or his brother Josef Čapek, whom Karel later credited as the actual originator of the word?

Open Robotics Engineering

Why It Is Open Karel Capek popularized robot in R.U.R. and is popularly credited with coining it, but in a 1933 letter responding to an Oxford English Dictionary etymology inquiry, Karel himself stated that his brother Josef suggested the word, derived from the Czech word robota, meaning forced labor.

What Would Settle It Corroborating primary correspondence or contemporaneous documentation, beyond the account Karel gave later, confirming the specific nature of the contribution Josef made.

Expertise Needed History of Technology

Petroleum Engineering Does the 1859 well Edwin Drake drilled at Titusville, Pennsylvania mark the true first oil well, or do earlier wells in Poland, Germany and Canada hold genuine priority?

Open Petroleum Engineering

Why It Is Open Drake is credited as the first American to successfully drill for oil, and the well he drilled launched the modern petroleum industry, but documented claims of prior art for oil drilling exist from Bóbrka, Poland in 1854, Wietze, Germany in 1857, and Oil Springs, Ontario in 1858, each predating the Drake well.

What Would Settle It An agreed definition of what counts as a genuine oil well, mechanically drilled rather than dug, and commercially significant rather than experimental, against which the historical record could be measured.

Expertise Needed History of Technology

Question posed in Edwin Drake (Wikipedia), Wikipedia contributors, Wikipedia, Edwin Drake, Career section.

Metallurgical Engineering Should Henry Bessemer or William Kelly be credited with inventing the pneumatic steelmaking process that founded modern metallurgical engineering, given that Kelly began experimenting before Bessemer filed his patent, yet went largely unrecognized?

Open Metallurgical Engineering

Why It Is Open Kelly experimented with injecting air into molten iron in the early 1850s, before Bessemer patented a similar process in 1855; after a financial panic in 1857, a company that had already licensed the Bessemer process purchased the Kelly patents outright and licensed both under the Bessemer name, and the documented record states that the role Kelly played in the invention has remained far less known.

What Would Settle It A settled historical account weighing the timing of independent invention against the commercial and patent outcomes that decided which name attached to the process.

Expertise Needed History of Technology

Question posed in William Kelly (Wikipedia), Wikipedia contributors, Wikipedia, William Kelly (inventor), lead section.

Nanotechnology Who should be credited as the founder of nanotechnology: Richard Feynman for his 1959 talk on room at the bottom, Norio Taniguchi for coining the term nano technology in 1974, or K. Eric Drexler for independently reviving and popularizing the term from 1981 onward?

Open Nanotechnology

Why It Is Open The talk Feynman gave is widely cited as the conceptual origin of nanotechnology, but many early nanotechnology researchers say it did not influence their own work and had not read it until much later; Taniguchi was the first to actually use the term nano technology, in 1974; and Drexler used the term again in 1981 without knowing of the earlier Taniguchi use, then went on to popularize it. Historians describe the status given to Feynman in the field as retroactively attached, to give nanotechnology a packaged history.

What Would Settle It A settled disciplinary consensus on whether founding credit belongs to conceptual precedent, to terminological coinage, or to later independent popularization.

Expertise Needed History of Technology

Question posed in History of Nanotechnology (Wikipedia), Wikipedia contributors, Wikipedia, History of nanotechnology, Norio Taniguchi section.

Mechanical Engineering Who deserves credit for inventing the four-stroke internal combustion engine cycle: Alphonse Beau de Rochas, who patented the concept in 1862 without building an engine, or Nikolaus Otto, who built the first working four-stroke engine in 1876?

Open Mechanical Engineering

Why It Is Open Alphonse Beau de Rochas, a French engineer, patented the theoretical concept of the four-stroke engine cycle in 1862 but never built a working engine. Nikolaus Otto built and commercialized the first successful four-stroke engine in 1876, unaware of the Rochas patent, and only lost part of his own German patent years later when Gottlieb Daimler's lawyer discovered Rochas's earlier description while searching for a way around royalty payments.

What Would Settle It A settled historiographical consensus on whether conceiving and patenting an unbuilt idea, or independently engineering and commercializing the same idea, carries the primary credit for founding the discipline; historians of technology continue to credit both figures for different reasons.

Expertise Needed History of Technology

Question posed in Nikolaus Otto (Wikipedia), Wikipedia contributors, Earlier patents section.

Marine Engineering Who deserves priority for inventing the marine screw propeller: Francis Pettit Smith, who patented his design on 31 May 1835, or John Ericsson, who filed an independent patent six weeks later?

Open Marine Engineering

Why It Is Open Francis Pettit Smith and John Ericsson began working on the marine screw propeller separately in Britain in 1835. Smith filed the first patent, on 31 May, while Ericsson, working independently, filed his own patent about six weeks later; each went on to build and demonstrate a working screw-propelled boat within the following two years.

What Would Settle It The historical record itself credits both men as independent parallel inventors rather than settling one point of priority; a documented consensus on whose contribution founded the technology, first patent versus first proven working demonstration, does not exist.

Expertise Needed History of Technology

Question posed in Propeller (Wikipedia), Wikipedia contributors, Screw propellers section.

Biomedical Engineering Who deserves primary credit for the first implantable cardiac pacemaker: Rune Elmqvist and Åke Senning, whose device was implanted in Sweden in 1958, or Wilson Greatbatch, whose independently developed device entered use in the United States in 1960?

Open Biomedical Engineering

Why It Is Open The first clinical implantation of a fully implantable pacemaker took place in Sweden on 8 October 1958, using a device designed by Rune Elmqvist and surgeon Åke Senning, but it failed within three hours and needed rapid replacement. Wilson Greatbatch's independently engineered implantable pacemaker, using a mercury-battery design, entered use in the United States in April 1960 and proved durable enough for his patient to live a further eighteen months.

What Would Settle It Whether the first, short-lived implant or the first durable design founded modern implantable pacemaker engineering is treated differently by different national and disciplinary histories, and no single source resolves which contribution carries primary credit.

Expertise Needed History of Technology

Question posed in Artificial Cardiac Pacemaker (Wikipedia), Wikipedia contributors, Implantable section.

Energy Engineering Who deserves credit for the first wind turbine to generate electricity: James Blyth, who built one in Scotland in July 1887, or Charles F. Brush, who built the first automatically operated one in the United States months later?

Open Energy Engineering

Why It Is Open In July 1887, Scottish academic James Blyth built and installed a battery-charging wind machine to light his own holiday home in Marykirk, Scotland. Months later, American inventor Charles F. Brush built what sources describe as the first automatically operated wind turbine for electricity production in the United States, after peer review of his design with local university professors.

What Would Settle It Whether Blyth's earlier but non-automatic machine or Brush's later but automatically operating turbine deserves credit as the first true wind turbine depends on which criterion, chronological priority or technical completeness, is taken as decisive, and sources do not agree on which should govern.

Expertise Needed History of Technology

Question posed in Wind Turbine (Wikipedia), History section, early wind turbines paragraph.

Agricultural Engineering Who deserves primary credit for the mechanical reaper: Obed Hussey, who patented his design in 1833, or Cyrus McCormick, who patented a competing design in 1834 and claimed an even earlier 1831 invention?

Open Agricultural Engineering

Why It Is Open Obed Hussey patented a mechanical reaper in Ohio in 1833. Robert McCormick's son Cyrus McCormick patented a competing reaper design in 1834, and Cyrus McCormick himself later claimed the machine was actually invented in 1831, which would predate Hussey's patent. The two designs competed in the marketplace for decades and were the subject of several lawsuits.

What Would Settle It A verified, independently documented date for the McCormick reaper's true first working version would settle whether Hussey's filed 1833 patent or McCormick's disputed 1831 claim has real chronological priority; no such independent record has been produced.

Expertise Needed History of Technology

Question posed in Reaper (Wikipedia), Wikipedia contributors, Mechanical reapers in the U.S. section.

Mining Engineering Who deserves credit for inventing the miners' safety lamp: Humphry Davy, honored by the Royal Society in 1815, or George Stephenson, who devised his own lamp independently the same year?

Open Mining Engineering

Why It Is Open Humphry Davy presented his safety lamp design to the Royal Society in London on 9 November 1815 and was awarded the society's Rumford Medal and two thousand pounds worth of silver. Engine-wright George Stephenson demonstrated his own, independently devised safety lamp down Killingworth Colliery a month before Davy's presentation, but his lamp was not developed and publicly credited until after Davy's paper, leading Davy to accuse him of theft.

What Would Settle It An 1833 House of Commons committee found that Stephenson had an equal claim to inventing the safety lamp, yet Davy went to his grave insisting Stephenson had stolen his idea; no single verdict has ever definitively settled priority between the two men.

Expertise Needed History of Technology

Question posed in Davy Lamp (Wikipedia), Wikipedia contributors, History section, Stephenson priority dispute paragraph.

Ocean Engineering Grand Lake St. Marys or Summerland: which really counts as the first offshore oil well?

Open Ocean Engineering

Why It Is Open Historians credit Grand Lake St. Marys in Ohio with the first submerged oil wells around 1891, drilled from platforms on piles into fresh water, five years before the Summerland field in Santa Barbara County, California drilled the first submerged wells in salt water in 1896. Whether ocean engineering should date the first true offshore well to the earlier freshwater lake wells or reserve the title for the first saltwater, open-ocean wells is a definitional choice historians have not settled.

What Would Settle It A documented contemporary industry or engineering definition of offshore drilling from the 1890s that explicitly includes or excludes freshwater lake wells would settle whether Grand Lake St. Marys or Summerland holds true priority.
