Before flash bulbs, flash photography relied on openly burning powder - usually containing magnesium. In 1893, Chauffour made an ancestor of the flash bulb; this had magnesium ribbon in a glass bulb, and was fired electrically- but this had been designed for underwater photography. The first recognisable flash bulb for general use was invented in 1925 by Vierkötter - using flash powder in an evacuated light bulb, fired by a lamp filament. Later that year, Vierkötter made a low-pressure-filled bulb. There are conflicting reports of the first commercial bulbs - made either by General Electric in the US, c.1927, or the Vacublitz alumimium foil bulbs made by Ostermeier in Germany, c.1929. The first wire-filled bulbs are reported to have been made by Philips in the Netherlands, in 1934.[1]

    I remember when I last bought a set, sometime in the late 70's I believe. Phil.

    I'm sure my kids would be puzzled by this old technology were you had to put in a new bulb every time you wanted to take another picture.
    The last time I saw one of these used was in 1978 at my sisters wedding, someone took a picture & the flash exploded with a loud bang. After everyone calmed down, the minister said "I didn't know this was going to be a shotgun wedding"
