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?
Scientist isolate DNA of the species they want to study. If a scientist want to learn about a particular gene in bacteria, they isolate the genomic DNA from the bacteria. By doing this you can have to total genes of bacteria in the test tube. By PCR or any other method one can study the gene present in the genome of the isolated species.
Why DNA isolated stored in buffer not water?
So as to maintain a favourable pH for the isolated DNA
First isolated DNA using pus collected from bandages at a local hospital since white blood cells are a major component of pus they were your source of DNA?
Friderich Miescher

What was the first that came out?
scientist prove that a chicken came first not the egg because of DNA
Did an African American contribute to the discovery of DNA?
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.
