Technology and Engineering Atlas
Claims this atlas currently marks as unsettled or as tested and found false. A debated fact is one scholars hold competing positions on; a debunked one has been checked against the record and found not to hold. Both are kept in view rather than quietly smoothed over, with the reasoning that put each one where it stands.

The current Wikipedia article treats just-in-time manufacturing as a principle within the Toyota Production System rather than a separately dated invention (the standalone just-in-time-manufacturing article now redirects to lean manufacturing); Toyota began building the Kaizen improvement teams that the Toyota Production System grew out of in 1936, but the pull-scheduling idea usually credited as JIT crystallized only over the following decades and the term itself was largely displaced by lean manufacturing during the 1990s.

A Czech priest and scientist built an actual grounded lightning rod in 1754, five years after Franklin first conceived the pointed design in 1749; sources describe an ongoing debate over priority for the invention.

1807 is the traditionally cited start of the modern profession, Robert Fulton's steam-powered vessel demonstration; the same source also dates the broader discipline to the early Industrial Revolution (early 1700s), and credits Archimedes as its first practitioner in antiquity, so no single origin year is agreed.

Interchangeable-parts manufacturing predates this by a century, but 1913 marks the Ford Motor Company introduction of the moving assembly line at Highland Park, the breakthrough most closely associated with mass production in its modern sense; the term itself was popularized by a 1926 Encyclopaedia Britannica article credited to Ford.

An earlier, apparently unrelated use of the word by the US company Servomechanisms, Inc. is recorded no later than 1951; the article credits Yaskawa Electric engineer Tetsuro Mori with creating the term, trademarked in Japan in 1971, treated here as the field's origin year.

Inventor of the compound microscope is genuinely disputed among historians: rival claims name Zacharias Janssen (1590, per his son's later account), Hans Lippershey (who applied for the first telescope patent in 1608), and Cornelis Drebbel (noted with a working example in London in 1619); no single claim is settled.

Dated here to Norio Taniguchi's 1974 paper, the first documented use of the word nanotechnology itself. Richard Feynman's 1959 lecture supplied the field's conceptual framing fifteen years earlier without using the term, and the field's modern popular identity and research agenda trace at least as strongly to K. Eric Drexler's independent 1981 coinage and 1986 book Engines of Creation as to Taniguchi's manufacturing-oriented usage; historians of science do not treat any single one of these three moments as settling when the field itself began.

Named inventors are all far later (a 1475 drawing by Francesco di Giorgio Martini; steam pile drivers credited to John Rennie in 1801 and James Nasmyth in 1845), but archaeological evidence places a comparable device at Scottish crannog sites roughly 5000 years ago; no single point of origin is established.

German engineer Christian Hulsmeyer patented a radio-echo ship-detection device as early as 1904, decades before radar became a working military technology, and Britain's 1935 Daventry Experiment was only one of several near-simultaneous, independently developed pulsed-radar programs in the 1930s, alongside parallel work in Germany, France, the United States and the Soviet Union; crediting any single nation or individual as radar's sole inventor understates how many independent teams reached a working system within a few years of each other.
