The popularity of the name from 12c. is probably due to immigration from Flanders, where St. Lambert of Maestricht was highly venerated. Attested as a surname from mid-12c.
A unit of luminance in the centimeter-gram-second system, equivalent to the luminance of a perfectly diffusing surface that emits or reflects one lumen per square centimeter. The lambert is named after the Swiss mathematician and physicist Johann Heinrich Lambert (1728-1777).
