Nucleic acids were named as such because they were first found in the cell nucleus. Robert Brown first coined the term nucleus when he discovered the cell nucleus in 1831. In about 1869 a phospohrus containing substance was found in the nucleus and called nuclein by Johann Friedrich Miescher. This was changed to nucleic acids over time as the acidic nature was discovered. The original "nucleus" came from Robert Brown. Thomas Avery discovered it was the genetic carrier in the 1940s.
