On January 29, 1991, Sharon J. Barnes, a chemist at Dow Chemical Company, along with her team, was granted U.S. Patent #4,988,211 for developing a process and apparatus for contactless measurement of sample temperature. This innovative technology allows for determining the temperature of a sample, such as urine, without direct contact, utilizing an infrared pyrometer. Barnes’s contribution exemplifies the significant impact of African American scientists in advancing technological innovations.
