Northern Sami was first described by Knud Leem ("En lappisk Grammatica efter den Dialect, som bruges af Field-Lapperne udi Porsanger-Fiorden") in 1748 and in dictionaries in 1752 and 1768. One of Leem's fellow grammaticians, who had also assisted him, was Anders Porsanger, himself Sami and in fact the first Sami to receive higher education, who studied at the Trondheim Cathedral School and other schools, but who was unable to publish his work on Sami due to racist attitudes at the time. The majority of his work has disappeared.
