During That Era

Back in the 1950's, toys were very simple and the child

had to use their imaginations to have fun considering

they were not electronic. With the invention of this longer lasting battery, toys became better and more advanced.

Also, things like radios and phones no longer needed to

be plugged into the wall. This made things

more convenient for most families.

The Contribution

How did he Improve Present

Day Life?

throughout the 1950's many engineers had experimented

with alkaline batteries but nobody had been able to develop a

longer running battery. Considering it cost

more to make a battery than they were worth back then.

By improving the alkaline battery's chemical

contents, he was able to revolutionize the battery

for the better. Allowing the battery's to have a longer life span and there for toys and appliances lasted longer and people were more satisfied with the product.

The Improvement

Wanting to improve the batteries faults,Urry

tested numerous chemicals such as

manganese dioxide and Zinc with the batteries

previous formula.

His main problem was that the battery could not provide enough power. Urry managed to overcome

this problem by using

powdered zinc

in the

batteries.

This combination of manganese dioxide

and zinc powder with an alkaline

substance outlasted regular

carbon-zinc batteries by

nearly 40 times.

Canadian Inventors

early Life...

Lewis Frederick Urry was born in Pontypool, Ontario on

January 29, 1927.

Urry graduated with a degree in chemical engineering from the University of Toronto in 1950. Having previously spent time serving in the Canadian army, he went to work for Eveready a few months after graduating.
