Phoebus Levene
Phoebus Levene sorts out DNA and RNA. Found out that DNA contianed adenine, guanine, thymine, cytosine, deoxyribose, and a phosophate group -

Linus Pauling
He mathematically made an anaylsis of X-Ray photos of protiens. He later said that DNA was a triple helix. -
Maurice Wilkins
Worked with Rosalind Franklin. Showed Watson and Crick Rosalind's photos of DNA which eventually lead to the discovery of the structure of DNA -
Erwin Chargaff
Made the Chargaff's Rules. These rules lead to the discovery of the double helix structure of DNA. The first is that the amount of guaninie equals the amount of cytosine. The next is that the amount of adonine equals the amount of thymine

Rosalind Franklin used x ray diffraction to create a picture of DNA. It was known as the B-Form This picture later was used to create a model of DNA's structure, a helix.
