1845 – Nurse and activist Mary Eliza Mahoney is born.

Mary Eliza Mahoney

After gaining her nursing diploma, Mahoney worked for many years as a private care nurse, earning a distinguished reputation. She worked for predominantly white, wealthy families. Majority of her work with new mothers and newborns had been done in New Jersey, with the occasional travel to other states. During the early years of her employment, African American nurses were often treated as if they were household servants rather than professionals. Mahoney emphasized her preference to eating dinner alone in the kitchen, distancing herself from eating with the existing household help, to further dismiss the relation between the professions. Mahoney also lived alone in an apartment in Roxbury where she spent time reading and relaxing, while also attending church activities with her sister. Nevertheless, families who employed Mahoney praised her efficiency in her nursing profession. Mahoney’s professionalism helped raise the status and standards of all nurses, especially minorities. Mahoney was known for her skills and preparedness. As Mahoney’s reputation quickly spread, Mahoney received private-duty nursing requests from patients in states in the north and south east coast.

After the postdoctoral fellowship, Johnson was appointed assistant professor of electrical and computer engineering at the University of Colorado Boulder in 1985, where she co-founded the National Science Foundation (NSF) Engineering Research Center (ERC) for Optoelectronic Computing Systems and spun off several companies from her research laboratory including ColorLink, Inc which was later sold to RealD, responsible for the technology that helped re-launch the 3D movie industry. Additionally, she co-founded the Colorado Advanced Technology Institute Center of Excellence in Optoelectronics. In 1999, Johnson was appointed Dean of the School of Engineering at Duke University, which would be later named for distinguished alumnus, Edmund T. Pratt Jr., CEO emeritus of Pfizer Corporation.
