Wikipedia has a good section on this:

DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it "nuclein".[117] In 1919 this discovery was followed by Phoebus Levene's identification of the base, sugar and phosphate nucleotide unit.[118] Levene suggested that DNA consisted of a string of nucleotide units linked together through the phosphate groups. However, Levene thought the chain was short and the bases repeated in a fixed order. In 1937 William Astbury produced the first X-ray diffraction patterns that showed that DNA had a regular structure.[119]

Why do scientist isolate DNA?

Scientists isolate DNA to study its structure, sequence, and function. By isolating DNA, scientists can analyze specific genes, create genetic maps, and understand how genes contribute to traits and diseases. Isolating DNA also allows for techniques like PCR and DNA sequencing to be performed.

No, DNA was first isolated by the Swiss physician. Also there were no African Americans involved in any subsequent work on DNA leading to the understanding of it structure.
