The individuals known for inventing the first electric light bulb are indeed Matthew Evans and Henry Woodward. They made significant strides in developing an early version of the electric light bulb in the 1870s. Their invention involved the use of carbon rods to produce light when electricity passed through, laying the groundwork for later advancements in electric lighting technology.
