Pete Souza

Capturing unguarded moments with Obama

As a staff photographer, for one and a half terms, his candid shots of "Dutch" and Nancy loosened the stiff collar of office, and brought humanity and intimacy to the administration.

When George H.W. Bush took over, Souza returned to freelancing. Years later he began covering a young senator from Illinois, who would one day assume the highest office in the land.

Since that day in January 2009, Souza has barely left President Obama's side.
