All of the above, plus the fact that the inside of the flash bulb contained some stuff that looked kind of like steel wool, but it was either made of magnesium or coated with magnesium powder. This is the stuff that sparklers are made of and it burns extremely quickly and brightly.

The flash guns in which they were mounted had a battery or batteries. The gun was connected to a special socket on the camera. When the shutter was fired the circuit closed, firing the bulb. Later, the 'hot shoe' was introduced which did away with the need for a lead. Now what was in the the bulbs, to make them burn brightly, I know not
