As with many other human inventions, photography is not the brainchild of just one person. Some people gave initial ideas, people took them further but missed them, and people made something out of it. Here you can read more about photography inventors.
William Henry Fox Talbot was many things, but the thing he is the most famous of is calotype, one of the earlier methods of photography which used paper as material and made negatives that can be copied many times.
Thomas Wedgwood didn’t live long, was ill all his life, and didn’t have much formal education, but he experimented with chemicals and planted a seed of photography as we know it today.
Nicéphore Niépce (born Joseph) was the first to experiment with photography successfully and set the foundations for future experimenters and photographers. His photographs needed a long time of exposure but could be fixed to last in light without darkening.
Louis Daguerre, the inventor of the daguerreotype, pushed photography (a young artist at the time) in the right direction by shortening the exposure time from a few hours to a few seconds.
