Molly Williams is recognized as one of the first recorded female African American firefighters in the United States. She was a slave owned by a man named Benjamin Aymar in New York City in the early 19th century. In 1818, Molly Williams was a member of Oceanus Engine Company #11, a volunteer firefighting company in Manhattan.

During a blizzard in February 1818, when many of the male volunteer firefighters were unavailable, Molly Williams took their place and helped pull the water pump to extinguish a fire in a building. She showed great bravery and strength in battling the blaze, earning the respect and admiration of her fellow firefighters. Molly Williams' actions helped save many lives and properties during her time as a firefighter.

Molly Williams' story serves as a reminder of the often overlooked contributions of African Americans, especially women, to the history of firefighting and public safety in the United States.
