In the 1960s, Phyllis Brown dared to do what few chromatographers did: to apply high performance liquid chromatography — then still in its infancy — to real samples, particularly complicated ones like blood. She did it because she had the vision to see the potential of the technique in the biological sciences.
In an interview with Karen M. Usher of West Chester University, Brown talks about what it was like to be a chromatography pioneer, and how she figured out what she had to do to get recognition in a male-dominated field.
