Who invented the first electric light bulb?

Discover Canada records this in one direct sentence. The guide writes: Matthew Evans and Henry Woodward — together invented the first electric light bulb and later sold the patent to Thomas Edison who, more famously, commercialized the light bulb. The two Canadians the test wants are therefore Matthew Evans and Henry Woodward.

Two inventors, one breakthrough. Discover Canada commits the invention of the first electric light bulb to Evans and Woodward — Canadian inventors. So the world-changing electric light starts with two Canadians, even though the bulb is most often associated internationally with Thomas Edison.

The patent went to Edison. Discover Canada writes that Evans and Woodward "later sold the patent to Thomas Edison who, more famously, commercialized the light bulb." So the historical credit follows a familiar pattern in invention history: the original inventors made the breakthrough, and a commercialiser scaled it. The original Canadian invention is what Discover Canada credits — even though Edison's name became more famous because he commercialised the product.

Evans and Woodward join a long Canadian inventor list. Discover Canada places them in its "Great Canadian Discoveries and Inventions" section alongside Alexander Graham Bell (the telephone idea), Sir Sandford Fleming (worldwide standard time zones), Sir Frederick Banting and Charles Best (insulin), Joseph-Armand Bombardier (the snowmobile), Reginald Fessenden (early radio), Dr. John A. Hopps (the first cardiac pacemaker), SPAR Aerospace / National Research Council (the Canadarm), and Mike Lazaridis and Jim Balsillie (the BlackBerry). The light bulb is one entry in this long Canadian-invention tradition — and the first electric bulb specifically is credited to two Canadians, even if Edison gets the popular fame.

The question is testing whether new citizens know who invented the first electric light bulb. Discover Canada commits to two Canadians: Matthew Evans and Henry Woodward. The right test answer matches that.

The wrong answer choices each pick a different inventor. The first and third options are not named in Discover Canada. Alexander Graham Bell is in the guide for the telephone idea, not the light bulb. Only Matthew Evans and Henry Woodward — two Canadian inventors — are credited with the first electric light bulb.
