Another technician and master photographer shares Nadar’s birthday:
Harold E. Edgerton (April 6, 1903 - 1990) invented a technique to use stroboscope light in photography and started producing amazing images…
In 1937 he began a lifelong association with photographer Gjon Mili, who used stroboscopic equipment, particularly a “multiflash” strobe light, to produce strikingly beautiful photographs, many of which appeared in Life Magazine. This strobe light could flash up to 1 million times a second. Edgerton was a pioneer in strobe photography, subsequently using the technique to capture images of balloons during their bursting, or a bullet during its impact with an apple, for example. He was awarded a bronze medal by the Royal Photographic Society in 1934, and the National Medal of Science in 1973. (Wiki)
