In 1849, the artist G. W. Woodward had a sketch of Caesar drawn as he sat dozing in a chair, which has since been lost.

In 1851, his final master's son persuaded Caesar to sit for a daguerreotype portrait, one of the earliest photographic images of an African American.

A note included with the portrait reads: "Ceasar [sic], born a slave of Van R. Nicoll, son of William, in 1737 at Bethlehem, N.Y., where he died in 1852.

The only evidence from Caesar's lifetime about his age is the 1850 census, which lists him as 110-year-old "Cesar Nicholls".

[3] If his age is confirmed, he would not only be one of the earliest-born people ever photographed (surpassing Conrad Heyer, John Adams and other such claimants), he would be one of the longest-lived Americans on record.
