The London Institution was an educational institution founded in 1806. It preceded the University of London in making scientific education widely available in the capital to people such as the Dissenters who were barred from attending Oxford University or Cambridge University.
The Institution moved into premises at Finsbury Circus in 1815 and was particularly noted for the teaching of chemistry. It closed in 1912 and the buildings were used for the University of London until their demolition in 1936.
