Molly Williams is believed to be the first known female firefighter in the United States. She was an African American woman who worked as a cook for Oceanus Engine Company Number 11 in New York City during the early 19th century. In 1818, when a fire broke out in the city, Molly Williams stepped in to help the firefighters by manning the water pump alongside them. Her bravery and dedication during this emergency earned her the nickname "Volunteer Number 11."

Molly Williams' actions paved the way for future generations of women and African Americans to serve as firefighters. Her story highlights the often unrecognized contributions of Black women in history, particularly in unconventional roles and professions. Molly Williams is a symbol of resilience, courage, and breaking barriers in the face of adversity.
