In the early 1900s, as the world braced for rapid industrial and military changes, materials like glass and metal were trusted allies. They served well in building aircraft, submarines, and medical tools. But when war became faster, machines sharper, and threats more complex, those once-reliable resources started showing cracks—literally.
Glass shattered under pressure. Metal corroded over time. And both weighed down the very aircraft meant to soar. Then came a moment of brilliance.
Then came a moment of brilliance.
In 1933, German chemist Otto Röhm introduced a groundbreaking material: Plexiglas®, created by polymerizing methyl methacrylate. Around the same time, DuPont’s team unveiled Lucite®, a crystal-clear, tough acrylic plastic with a 93% transparency rate and resistance to water and UV rays.
Just in time for war.
World War II thrust these materials into the spotlight. Both Allied and Axis forces used Plexiglas®. American B-17 bombers carried ball turrets made from Plexiglas®, where the smallest crew members scanned the skies for enemy fighters. German aircraft, such as the Heinkel HE 111, featured Plexiglas® canopies and nose panels.
What made this story even more extraordinary was that Rohm and Haas—the company behind Plexiglas®— had operations on both sides of the Atlantic. Otto Haas had moved to Pennsylvania decades earlier, ensuring the American branch supported the Allies. Meanwhile, the German branch supplied Plexiglas® for the Luftwaffe and Wehrmacht. It was a rare case of science serving both sides of a divided world.
Lucite®, lighter than glass and tougher than other plastics became the darling of aircraft design. It appeared in canopies, bubble-tops, boat windshields, and post-war innovations, such as camera lenses, taillights, and even medical equipment.
But the story didn’t end when the war did.
Over time, acrylics like Plexiglas® and Lucite® became everyday materials. Screens, lenses, virtual reality headsets, building panels, retail signage, jewelry, and art installations—these applications demonstrate the remarkable advancements in the materials.
What began as a solution to wartime fragility evolved into a symbol of progress and creativity.
From ball turrets to art galleries, Plexiglas and Lucite remind us that when we innovate for survival, we often uncover tools that redefine everyday life.
