Nobody invented infra-red or infra-red lights as such. Infra-red is radiant heat and is a natural phenomenon and is emitted by essentially all light sources. Infra-red devices with no visible light emissions, are, in their simplest form, radiant heaters. What was invented were ways to use IR for night-vision - often called image intensifiers.
