A few years ago the American Chemical Society put together an education page highlighting the contributions of African Americans to the chemical sciences. By no means was this an exhaustive list, but it illustrates the creative depth and passions an array of people contribute to chemistry. Take some time to explore the ACS list, search the literature or peruse the publications at the National Organization of Black Chemists and Chemical Engineers (NOBBChE).
This past November Dr. Warren Washington received the National Medal of Science for his work on the development of computational climate models. Two of his creations were used extensively by the IPCC in their 2007 report. Dr. Washington is a renown climate modeler and his biographical profile with the National Center for Atmospheric Research can be found here. You will also find a variety of other links, including multimedia resources, regarding Dr. Washington on the page.
Enjoy celebrating chemistry and Black History Month.
