Pär Aron Borg (4 July 1776 in Avesta – 22 April 1839) was a Swedish pedagogue and a pioneer in the education for the blind and deaf.
Borg was a teacher. After having seen a play where a deaf boy communicated by gestures, he was inspired to create a manual alphabet. He began to educate deaf and blind students regularly in 1808. He founded Allmänna institutet för Blinda och Döfstumma (The Public Institute of the Blind and Deaf) in Stockholm in 1809 with protection from the Queen, Hedwig Elizabeth Charlotte. His perhaps most famous student was Charlotta Seuerling. The school had deaf teachers, and the education was given by sign language. He made a trip to Portugal in 1823–28, were he founded a school for the deaf; thereby, Portugal was given the same manual alphabet as Sweden.
