The Canadian scientist who first patented kerosene in 1854 was?

• A. Abraham Gesner
• B. John Maclure
• C. James Dewar
• D. Michael Faraday

Answer: (A)

Kerosene as a refined lamp fuel was introduced by Abraham Gesner, a Canadian scientist. He developed a method to distill a clean, smokeless liquid from coal oil and secured the first patent for this process in 1854. This made kerosene a practical, cheaper alternative to whale oil and helped establish it as the standard lamp fuel of the era. The other names mentioned were notable scientists in different fields, but none are credited with patenting kerosene in 1854.
