Humphry Davy created the first incandescent light by passing current through a platinum strip. It caused a glow and did not last long, but marked the beginning of incandescent light development. Experimenters continued over the next 70 years to use platinum and iridium. Frederick used a platinum filament in an evacuated glass tube to make a light bulb. . at a glance.
