Claim to Fame:
Urry was a Canadian chemical engineer who invented the alkaline and lithium battery. While working for the Eveready battery company, he was attempting to extend the life of the current battery technology. He found a combination of manganese dioxide and zinc powder with an alkaline substance outlasted regular carbon-zinc batteries by nearly 40 times. Lithium batteries use lithium as the anode of the battery and can supply higher voltages and last longer than alkaline batteries.
