Abraham Lincoln (1809 – 1865) was the 16th President of the United States, serving from March 1861 until his assassination in April 1865. Lincoln most notably led the United States through the constitutional, military and moral crisis during the American Civil War.
After foiling a plot to assassinate him – who would later hire the agency as his personal 'secret service' during the American Civil War – Pinkerton garnered a reputation as America's go-to office for counter-intelligence and security operations.
- During his time in captivity as a subject for the Abstergo Industries' Animus Project, Clay Kaczmarek relived the lives of his ancestor who fought during the Battle of Gettysburg, and overheard Lincoln's famous Gettysburg Address.
- Abstergo Entertainment supervisor Melanie Lemay had a great-great-grandfather who was known to have come into contact with Lincoln a number of times as a Union soldier during the Civil War.
