Did Edison Briefly Forge Graphene in 1879?

Rice University researchers suggest Thomas Edison may have accidentally produced graphene in 1879 while testing carbon‑filament light bulbs with flash Joule heating; their experiments on bamboo filaments showed transient graphene formation that would quickly convert to graphite, implying Edison could have created a modern “wonder material” long before graphene’s official isolation.

Century-old bulb experiment hints Edison seeded graphene

Rice University researchers replicated Edison’s 1879 carbon‑filament bulb method and, using modern analysis, found evidence that turbostratic graphene formed in the heated carbon filament; while not definitive proof Edison himself produced graphene, the study shows how re‑examining historical experiments with current tools can reveal overlooked materials and spur new questions.
