Who is the inventor of plexiglass?
Although some people claim that a Canadian named Dr. William Chalmers invented the plexiglass in 1931, there is evidence that he was not in fact the originator of the idea. There were two German inventors who started working on plexiglass long before 1931. Their names were Dr. Walter Bauer and Dr.Otto Rohm.

What was needed to make bulletproof glass?
Alternating layers of glass and plastic resin. Truly bulletproof glass must be at least 4 to 6 inches thick! I've seen samples of such glass from WW2 bombers in museums. Modern bulletproof "glass" probably uses plexiglass plastic instead of real glass though. Note: a thick enough piece of ordinary glass is bulletproof by itself. Telescope mirrors (several feet thick) have been shot and although damaged the bullet did not pass through and after removing the bullet, drilling out the hole, and painting the inside of the hole black the telescope was returned to operation with no detectable loss of function.
