Which inventor is associated with an 1892 patent for an improvement to the rotary engine?

• A. Andrew Jackson Beard
• B. Thomas W. Stewart
• C. Lincoln F. Brown
• D. John Lee Love

Answer: (A)

Rotary engines use a rotating element to produce power rather than pistons moving back and forth, so improvements to this design aimed to make the engine smoother, more reliable, and more efficient. An 1892 patent for improvements to the rotary engine marks a notable moment in making that kind of engine more practical, and Andrew Jackson Beard is the inventor associated with that patent. This places Beard in the history of African American inventors contributing to late-19th‑century engine and transportation technology. The other names are known for different inventions or achievements, which is why this particular patent connection is attributed to Beard.
