Monsanto MV1  
Written by Accutron on 2007-05-06  

Introduced in 1969, the Monsanto MV1 is generally considered to be the first commercially viable visible LED. Unlike modern LEDs, the MV1 is packaged in a gold-plated metal canister with an epoxy lens. The MV1's internal construction consists of an 'anvil head' contact surface, upon which a square GaAsP die with a circular aperture is mounted. Like other early LEDs, the MV1 is an extremely dim device, only barely visible under indoor lighting.

Monsanto later introduced the MV2, a GaP green device.
