Abraham Gesner was awarded a U.S. patent for ‘Improvement in processes for making kerosene.’

Around 1849–1850, Abraham Gesner coined the term “kerosene.”

By 1854, he had commercially introduced kerosene and received U.S. Patents Nos. 11,203–11,205 for improvements in kerosene burning fluids.

On 27 March 1855Abraham Gesner was awarded a U.S. patent No. 12,612 for improving the process of making kerosene.

The 1855 patent focused on refining and purifying kerosene from substances like coal, bitumen, and shale.

This patent made kerosene a cleaner, safer, and more efficient fuel for lamps.

Gesner patented the process of producing kerosene, not the substance itself.

His work helped reduce dependence on whale oil and contributed to the growth of modern fuel industries.
