Etienne-Jules Marey

"A forerunner of the motion picture camera, it had a sight and a
clock mechanism and made 12 exposures of 1/72th of a second
each. Marey’s observations about the changes in the shape of
birds’ wings in relation to air resistance were vital in understanding
the phenomenon of flight."
