Which came first?  The battery or the flashlight?

The foundation of portable power – the 
battery – found its earliest and most popular 
use powering a device invented shortly after 
the battery – the handheld flashlight. It began 
in 1898 when Conrad Hubert, a Russian 
immigrant, lit up New York City with the 
introduction of the newly patented handheld 
flashlight. Soon afterward, Hubert began 
manufacturing flashlights, batteries and light 
bulbs under the name “Ever Ready” – and now 
more than 110 years later, Energizer is still the 
innovative leader in portable lighting technology.

Hubert’s first portable flashlights were 
handmade using a dry cell battery, bulb and 
rough brass reflector inside a paper tube. 

Putting these flashlights to work in the 
hands of New York City policemen 
resulted in high visibility and nearly 
instantaneous success for his product.

 
Over the years, emerging bulb and 
battery technology helped Eveready 
Battery Company, Inc. move forward in 
flashlight development 
– introducing the 
tungsten bulb, 
improving switches 
and developing 
spotlights to project 
light forward.
