Konstantinos Agathophron Nikolopoulos (Greek: Κωνσταντίνος Αγαθόφρων Νικολόπουλος; c. 1786 – 12 June 1841) was a Greek composer, philologist and colleague of Adamantios Korais.
[1] Konstantinos Nikolopoulos was born in Smyrna, Ottoman Empire and grew up in Paris.
Being somewhat of a "Renaissance Man" (that is, an individual with many varied skills and talents), he was employed as librarian in the French Institute, where he worked for much of his life.
He died in Paris, at the age of 55,[2] while he donated his library to the municipality of Andritsaina, origin place of his father.
Some of his works were based on Ancient Greek texts, while he composed also religious music.
