Pioneers of Power: Celebrating Black Leaders in Energy and Sustainability
Black History Month is more than just a time to reflect, but a chance to celebrate the humanity and contributions that generations of African Americans have made across American society.
In the collective spirit of Black History Month, Exelon is proud to be an industry leader because of the contributions made by employees from a diverse range of experiences and backgrounds.
While Black History Month offers the opportunity to remember and appreciate the great contributions to American society, it is also a chance for the energy industry to acknowledge and recognize African American contributions that have shaped our past and present.
This year, we’re celebrating a select group of African Americans for their leadership, innovations and talents that shaped the energy industry. The impact of these leaders from both past and present continue to ensure a stronger, cleaner and brighter energy future.
Lewis Latimer

Lewis Latimer (1848-1928) was an inventor and expert draftsman who joined Thomas Edison’s lab in 1884. He is one of the pioneers in the electric light industry, seeing it from its infancy until it became a global feature. His work helped to improve Edison’s initial invention and patented the use of carbon filament that would open the door to widespread public use. Latimer worked with Alexander Graham Bell to draft the patent for Bell’s design of the telephone until he was hired by the Edison Electric Light Company. Latimer also published a book titled Incandescent Electric Lighting: A Practical Description of the Edison System.

She also served in leadership roles for President’s Ford and Carter and was named assistant administrator for conservation and environment in the Federal Energy Administration (FEA) in 1977. When the FEA joined the Department of Energy (DOE), she served as chief of the DOE’s Economic Regulatory Administration. Throughout O’leary’s time with the government, she worked to ensure funding, resources and innovation-focused energy policies that expanded efficient and renewable energy. Following her career in public service, she also served as president of Fisk University, her undergraduate alma mater and a historically Black college.
