We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Sakichi Toyoda — The 5 Whys technique is often attributed to Sakichi Toyoda, but it was developed and popularized by Taiichi Ohno as part of the Toyota Production System, not directly by Sakichi Toyoda himself.
Seymour Cray — Cray worked on breaking Japanese naval codes in the Pacific theatre
Shuji Nakamura — The entry states Nakamura 'helped invent the blue LED' and is 'co-inventor of the blue LED', but the phrasing could imply he alone or primarily invented it, whereas the invention is collectively attributed to Akasaki, Amano, and Nakamura.
Shuji Nakamura — The entry says 'He holds 208 US utility patents as of May 5, 2020' — this specific number and date are not verifiable from widely known canon and may be outdated or inaccurate.
Sylvester H. Roper — The entry states Roper worked for the Springfield Armory during the Civil War; this is not well-documented in standard biographies and may be an invented claim.
Vladimir Shukhov — Shukhov did not study under Pafnuty Chebyshev at the Imperial Moscow Technical School; Chebyshev taught at Saint Petersburg University, not Moscow.
Vladimir Shukhov — The claim that Shukhov's 1891 patent definitively invalidated Standard Oil's Burton process is an overstatement; the relationship between the patents is complex and disputed.
Wallace Carothers — Carothers was the oldest of four children, but he was actually the oldest of five children (he had four younger siblings).
Werner von Siemens — The entry claims he invented the electric tram, trolley bus, electric locomotive, and electric elevator, but these had earlier precursors, making the attribution of 'invention' a factual overstatement.
Werner von Siemens — The entry says he claimed invention of the dynamo, but the dynamo was invented earlier by others; his contribution was improving it, not inventing it.
Wilhelm Maybach — The entry states that the Mercedes car was introduced in 'late 1902', but the first Mercedes (the Mercedes 35 hp) was introduced in 1901, not late 1902.
Wilhelm Maybach — The entry states that Maybach 'drove the world's first motorcycle, the Reitwagen, in November 1885'. Historically, Gottlieb Daimler is credited with riding the first motorcycle, not Maybach.
