The GREAT Abolitionist Mary Meachum died in St. Louis, Missouri sometime in August 1869. A former slave, She was approximately 68 years old.

"Mary Meachum, together with Her Husband John Meachum, helped free enslaved Africans born in America on the Underground Railroad through their home and church. Her Husband's carpentry business gave them the ability to purchase those enslaved and free them, teaching them the trade so that they could support themselves in their new lives.

Meachum was born into Slavery in Kentucky, in 1801. Her freedom was purchased by Her Husband, who had earned enough money to purchase His own freedom before they married. They began a school to educate free and enslaved Africans in the First African Baptist Church. However, the state of Missouri banned education for Blacks, so in 1847 they relocated to a floating steamboat on the Mississippi River. After her husband died in 1854, Meachum continued running their home as a "safe house" on the Underground Railroad. On May 21, 1855, after an attempt to ferry nine enslaved people across the Mississippi River to freedom in Illinois, Meachum was arrested for breaking the Fugitive Slave Law of 1850 and charged in court with slave theft.

It was reported that Mary was tried by a jury and acquitted of at least one charge, and the remaining charges were dropped. The Mary Meachum Freedom Crossing in St. Louis named after Her, was the first site in Missouri to be accepted in the National Park Service's National Underground Railroad Network to Freedom." - Smithsonian National Museum of African American History & Culture.

As for the photo that Winn Forman has posted to this memorial, this is what Daughter of the American Revolution (49848768) has to say about it:

The photo is not Mary Meachum as the internet would have people believe. This image is from the Library of Congress of an unknown woman from Georgia that was collected by W.E.B. Dubois in or around 1900 for an exhibit at the Paris Exhibition illustrating the progress of African Americans one generation removed from slavery. Info from Angela de Silva of the National Black Tourism Network in St. Louis, Missouri.
