I was curious about Jacques-Henri Lartigue so I searched more information about this extraordinary photographer online.
A very pleasant article on Museyon tells his fascinating story and who he was:

This is a complimentary extract from the book French Riviera and Its Artists: Art, Literature, Love, and Life on the Côte d’Azur by John Baxter, from which also the photo below.
Harold Edgerton invented the electronic flash combining his love for photography with that for electricity and his story is told in a BBC article, at: http://www.bbc.com/future/story/20140722-the-man-who-froze-the-world (Accessed 9/05/2017).
Another article in www.britannica.com explains how a flash lamp works and how it can be used to produce brief, intense emissions of light useful in photography and in the observation of objects in rapid motion.

On Edweard Muybridge:
The first source online is the website dedicated to him:

These collotypes have been animated, and it’s self-evident how Muybridge could have been an inspiration for the Lumière brothers in starting their experiments leading eventually to the invention of cinema.

Interesting experiments have been made also in reverse: instead of breaking down time into sequential images, photography can ‘compress time’ by taking multiple images and superimposing them all into one frame (Creative Arts Today, page 159).
