“Face-to-Face Portrait Talks” will pair a speaker with one portrait and discuss its meaning, pose, history and artistic methods in a 30 minute lecture. The series starts Thursday with Beth Turner, vice provost for the arts at the University of Virginia, talking about Alexander Calder.

On July 14 Susan Eisenhower, the granddaughter of President Dwight D. Eisenhower, will focus on a portrait of Mamie Eisenhower. Then on July 21 Sid Hart, the senior historian at the Portrait Gallery, will discuss the recently acquired portrait of baseball star Pedro Martinez.

This month’s talks wrap up July 28 with Martin Sullivan, the museum’s director, speaking about John Updike.

The free talks will be held on Thursdays from 6 p.m. to 6:30 p.m, with visitors gathering in the F Street lobby of the building.
