Which individual is credited with developing carbon fibers in the material context?

• A. Thomas Edison
• B. Nikola Tesla
• C. Marie Curie
• D. Alexander Graham Bell

Answer: (A)

Carbon fibers in this context refer to the carbon filament material used in incandescent lighting. Thomas Edison played a pivotal role by optimizing and commercializing carbon filaments, making them durable enough to operate for extended periods. He conducted extensive experimentation, showing that carbonized natural fibers—such as bamboo and cotton—could provide the right balance of conductivity and resistance at high temperatures. This breakthrough made practical electric lighting possible and established carbon fibers as a viable filament material. The other figures are known for different landmark contributions—Tesla for electrical systems, Curie for radioactivity research, and Bell for the telephone—so their work did not center on developing carbon filament materials.
