Who invented bulletproof glass first made?

Bulletproof glass was first developed in the late 19th century by Édouard Borel, a French chemist, who created a laminated glass by sandwiching layers of glass and polymer materials. However, the more practical versions of bulletproof glass that we recognize today were refined in the mid-20th century, with significant contributions from various manufacturers and researchers. The advancements in materials science have since led to the modern iterations used in security applications.
