The law was discovered by Pierre Bouguer before 1729. It is often mis-attributed to Johann Heinrich Lambert, who cited Bouguer's âEssai d'Optique sur la Gradation de la Lumiereâ (Claude Jombert, Paris, 1729) â and even quoted from it â in his âPhotometriaâ in 1760. Much later, August Beer extended the exponential absorption law in 1852 to include the concentration of solutions in the absorption coefficient.
