Flashlight Powder
Blitzlichtpulver or flashlight powder was invented in Germany in 1887 by Adolf Miethe and Johannes Gaedicke. Lycopodium powder (the waxy spores from club moss) was used in early flash powder.
Flashbulbs
The first modern photoflash bulb or flashbulb was invented by Austrian, Paul Vierkotter. Vierkotter used magnesium-coated wire in an evacuated glass globe. Magnesium-coated wire was soon replaced by aluminum foil in oxygen. On September 23, 1930, the first commercially available photoflash bulb was patented by German, Johannes Ostermeier.
