三位塑造現代基礎設施的黑人創新者
「黑人歷史月」是我們反思非裔美國人豐富的文化遺產、堅韌精神與卓越成就的時刻，他們所產生的影響持續激勵著一代又一代的人。我們很榮幸能透過介紹三位對能源產業及現代基礎建設發展產生深遠影響的先驅人物，來慶祝黑人創新者在歷史長河中所作出的重大貢獻。
David Crosthwait – Mastering Indoor Climate Control
David Crosthwait was a mechanical and electrical engineer, inventor, and writer whose expertise revolutionized indoor climate control. As the first Black American fellow of the American Society of Heating, Refrigeration, and Air Conditioning Engineers, Crosthwait held over 35 U.S. patents and 80 foreign patents. His innovative heating and ventilation designs were instrumental in enhancing indoor environments for large buildings, including Radio City Music Hall and Rockefeller Center. His work continues to influence modern climate control systems.
Lewis Latimer – Illuminating the World
Best known for improving Thomas Edison’s light bulb, Lewis Latimer invented a longer-lasting carbon filament in the 1870s, making electric light more practical and affordable. His contributions helped expand public lighting infrastructure worldwide. Beyond his technical expertise, Latimer authored the first book on electric lighting and played a key role in bringing electricity to homes and businesses across the globe.
Sophie Maxwell – Champion for Environmental Justice
A former electrician and dedicated public servant, Sophie Maxwell served three terms as San Francisco’s District 10 Supervisor. She played a pivotal role in advocating for environmental justice and equitable resource distribution, working alongside community advocates and city officials to close the Hunter’s Point and Potrero Hill Power Plants. After serving as an SFPUC Commissioner, Maxwell continues her work to advance clean energy initiatives and promote sustainability for all San Franciscans.
Many of today’s energy innovations would not exist without the groundbreaking work of African American pioneers. Their perseverance and ingenuity remind us that diverse perspectives and leadership are essential in shaping an equitable, clean energy future.
While Black History Month is a dedicated time for reflection and recognition, the achievements, stories, and voices of Black Americans must be uplifted year-round. That’s why this is the first article in a series that we’re planning to spotlight people, both past and present, who have made important, and often unrecognized, contributions connected to the SFPUC’s work of delivering clean drinking water, wastewater services and electrical power.
