Woodward and Evans Light Bulb

In 1874, Canadians Henry Woodward and Mathew Evans patented a design for an incandescent light bulb. Their invention preceded that of American Thomas Edison by several years. In fact, the second patent (issued in 1876 in the United States) was among those that Edison bought as he refined the technology to create a longer-lasting bulb. Woodward and Evans’s early work on the light bulb in Toronto has gone largely unrecognized. It was nevertheless an important development in the invention of electric lighting.

Roland Galarneau

Roland Galarneau, CM, machinist and inventor (born 16 February 1922 in HullQuebec; died 22 May 2011 in Hull). In the late 1960s, Galarneau invented the Converto-Braille, a computerized printer capable of transcribing text into Braille at 100 words per minute. This was a landmark innovation for people with visual impairments, as it increased their access to textbooks and other written information. Galarneau developed faster versions of the Converto-Braille in the 1970s. The company he founded eventually adapted the machine into software for IBM computers in the 1980s. This software was a precursor of the Braille software used today.
