About this source
What it is
This group photograph, taken around 1859 in Mathew Brady's studio, shows President Buchanan with his cabinet: Jacob Thompson, Lewis Cass, John B. Floyd, Buchanan himself, Howell Cobb, Isaac Toucey, Joseph Holt, and Jeremiah S. Black. It is held by the Library of Congress.
Why it matters
The photograph captures the men who advised Buchanan during the crisis years before the Civil War. Several of them, including Cobb, Floyd and Thompson, were Southerners who later took roles supporting secession, a fact that has shaped later judgments of Buchanan's administration and its loyalties as the Union came apart.
Look closer
- What can you tell about the men's roles and relationships from how they are posed in the studio?
- Why might knowing what each man did later change how we read this photograph today?
- What is missing from a formal group portrait like this that written records might reveal instead?
