Mary Todd came from a prosperous Kentucky family, received an outstanding education.
Her interest in politics began early and she was considered more determined and politically ambitious than Abe.
Mary was also an ardent abolitionist and brought the horror of slavery to President Lincoln's attention.
A frequent visitor to army hospitals during the war she endeared herself to the wounded, bringing gifts and writing letters for them.
Depicted as a Southern traitor, her misery increased with son Willie's death and the horror of Abraham Lincoln's assassination.
The death later of a third son, Tad hastened her own, and she died in her sister's house where she had married Lincoln years before.
