Black Invention Myths, Checked

Each entry: the claim as it circulates, CTL's verdict, and what is actually documented. Full text is carried verbatim from the flagship's entity myth audits.

1. Benjamin Banneker

Claim as circulated: Benjamin Banneker invented the clock / built the first clock in America. Verdict: Exaggerated. Banneker did build a working all-wooden striking clock ~1753 by studying a borrowed pocket watch — extraordinary for a self-taught 22-year-old. He did not invent the clock, and his was not the first American-made clock; colonial clockmakers had worked for over a century. His documented scientific achievements are the almanacs and astronomical predictions.

2. Elijah McCoy

Claim as circulated: The phrase 'the real McCoy' comes from railroad engineers demanding Elijah McCoy's genuine automatic lubricator. Verdict: Unverifiable. McCoy's invention record is fully confirmed: the 1872 automatic lubricator (US 129,843) was a major industrial success widely copied. But the famous phrase origin is NOT established — every careful source hedges ('suspected, though not confirmed'). The honest grade is Unverifiable, which is itself the finding: the legend outruns the evidence.

3. Garrett Augustus Morgan

Claim as circulated: Garrett Morgan invented the traffic light. Verdict: Exaggerated. Morgan did patent a genuinely novel three-position traffic signal (US 1,475,024, 1923) whose all-directional-stop position was an important safety innovation, and he sold it to GE. He did not invent the traffic light: gas-lit signals date to 1868 London, electric signals to 1912-1914, and his own device used semaphore arms, not lights. The 'invented the yellow light' claim is unsupported.

4. Garrett Augustus Morgan

Claim as circulated: Garrett Morgan invented the gas mask. Verdict: Exaggerated. Morgan was a genuine inventor: he patented a novel smoke hood (US 1,090,936, 1914), won first prize at the Second International Exposition of Safety and Sanitation, and heroically used it in the 1916 Lake Erie tunnel rescue. He did not invent the gas mask — respirators date to the mid-1800s. Claims of WWI military use are unverified.

5. George Washington Carver

Claim as circulated: George Washington Carver invented peanut butter. Verdict: False. Carver never invented peanut butter — it was patented in 1884 (Edson, US 306,727) and 1895 (Kellogg, US 580,787) before his peanut work began. His real, documented legacy is far broader: 300+ peanut products, crop-rotation advocacy, the Jesup Wagon extension work, and only three patents total — a deliberate choice, as he believed discoveries should be available to all.

6. Granville T. Woods

Claim as circulated: Granville Woods, the 'Black Edison,' invented the multiplex telegraph, the third rail, and the air brake — and beat Edison in court twice. Verdict: Exaggerated. Woods was a major inventor (~45 patents) whose induction-telegraph patents were real and who prevailed over Edison in Patent Office interference proceedings — the nickname had a factual basis. But 'invented the third rail,' 'invented the air brake,' '60+ patents,' and 'beat Edison in court' are all inflated: his were improvement patents, and the contests were administrative interferences.

7. Lewis Howard Latimer

Claim as circulated: Lewis Latimer invented the light bulb / the carbon filament that made the light bulb work. Verdict: Exaggerated. Latimer was a real engineer-inventor with genuine patents — including a carbon-filament manufacturing process (US 252,386, 1882) used at Maxim's company — and a remarkable career (Bell's telephone patent draftsman, lighting-system installer, Edison Pioneer, patent-litigation expert). He did not invent the light bulb or the carbon filament; both predate his work.

8. Lonnie G. Johnson

Claim as circulated: Lonnie Johnson, NASA engineer, invented the Super Soaker. Verdict: Confirmed. Johnson is a verified inventor-engineer-entrepreneur: the Super Soaker patent is unambiguous, his NASA/Air Force engineering career is documented, and his 100+ patents are a matter of record. Included as the calibration case — this is what a 'Confirmed' verdict requires.

9. Madam C.J. Walker

Claim as circulated: Madam C.J. Walker invented the hot comb / chemical hair straightener. Verdict: False. Walker invented neither the hot comb nor chemical straighteners — she explicitly denied claiming to straighten hair, calling herself a 'hair culturist.' The comb predates her. Her documented achievement is entrepreneurial and cultural: the Walker System, a manufacturing company, beauty schools, and a national agent network.

10. Otis Boykin

Claim as circulated: Otis Boykin invented the (heart) pacemaker. Verdict: Exaggerated. Boykin was a genuine electronics inventor whose precision resistors and stimulator control unit made devices — including pacemakers — smaller, cheaper, and more reliable. He did not invent the pacemaker; that was a multi-actor medical-device effort (Elmqvist/Senning, Greatbatch, Bakken). Component-level invention is real invention, but it is not system invention.

11. Philip Emeagwali

Claim as circulated: Philip Emeagwali invented the Internet / is a father of the Internet. Verdict: False. Emeagwali did real parallel-computing application work that won a 1989 Gordon Bell Prize in the price/performance category for oil-reservoir modeling on a Connection Machine he did not invent. Every grander claim — father of the Internet, Nobel of computing, Newton's laws — is contradicted by the prize's own namesake and judges.

12. Shirley Ann Jackson

Claim as circulated: Dr. Shirley Ann Jackson invented caller ID, call waiting, touch-tone phones, fiber-optic cables, and solar cells. Verdict: False. Jackson is a distinguished theoretical physicist and institutional leader — first Black woman MIT physics PhD, NRC chair, RPI president, National Medal of Science. She did not invent caller ID, touch-tone phones, fiber optics, or solar cells; those claims are unsupported by her publication and patent record.

How to quote this

Quote the verdict + the documented correction together — never the verdict alone. The correction is the useful part: it replaces a false claim with a stronger true one.
