Nuclein was discovered by Friedrich Miescher in 1869
Explanation
In the somewhat early 1880s Albert Kossel further purified the substance and discovered its highly acidic properties. Then he later discovered the nucleobases. In 1889 Richard Altman creates the term nucleic acid. Friedrich Miescher was the first scientist to ever isolate nucleic acid.
