the drawings from woodward's 1876 united states patent are almost identical to those that appeared in woodward and evan's 1874 canadian patent. the carbon burner, a "most important feature of a practical lamp" differs widely from edison's filament. several earlier inventors working on the light bulb had progressed as far in their work as woodward and evans: marcellin jobard in 1838, c. de changy in 1856, john wellington starr in 1845 and joseph swan in 1860. each contributed to the development of the incandescent lamp, but it was edison who assembled the necessary components to make the first practical electric light bulb.
