Lewis F. Urry (ChemE 5T0)

After graduating from Chemical Engineering at U of T, Lewis F. Urry began working for the Eveready Battery Company (later named Energizer in 1980), where he invented the alkaline battery.

Over the course of his life, Urry held more than 50 patents including several for the lithium battery — the source of energy for many of the electronic devices we use today.

His prototype alkaline battery and first commercially produced cylindrical battery is displayed next to Thomas Edison's light bulb at the Smithsonian Institution Museum of American History.

Approximately 80% of all dry cell batteries used in the world are based on Urry’s work.
