Not All Chemists Are White Men

Academics / Departments & Programs / Chemistry & Biochemistry / Not All Chemists Are White men

In most chemistry classes, students are only taught about white male chemists (like Dalton, Thompson, Rutherford, and Bohr). While it is important to learn about these men and their work, by exclusively talking about them, it can give the impression that it is only white men who have made significant contributions to chemistry. There are, however, many people of color and women that have made great innovations in chemistry and other related fields. The following scientists are all people of color and women who have done significant research in the field of chemistry.

For chemists indicated by a (*), we created an application problem connecting their work to a general chemistry topic which is compiled in a PowerPoint, available here: Powerpoint.

Tu Youyou*

  • Born in 1930 in Ningbo, China.
  • Contracted tuberculosis at 16, which motivated her to go into the medical field.
  • Graduated from Beijing Medical University School of Pharmacy.
  • Found an ancient Chinese herbal remedy – "take one bunch of Qinghao (wormwood), soak in two sheng (~0.4 liters) of water, wring it out to obtain the juice and ingest it in its entirety" – and perfected the extraction process to produce pure artemisinin crystals at a high yield.
  • Pure artemisinin is a very cheap anti-malarial drug that has saved millions of lives.
  • Took the new extracts herself for the safety evaluation in order to begin the clinical trial during peak malaria season, rather than waiting another year.
  • Won the Nobel Prize in 2015 for this work, making her the first Chinese woman to do so.
