The National Gallery of Art has received 45 unique photographs by the celebrated photographer Harry Callahan from his family. The gift makes the Gallery one of the leading repositories of Callahan’s work.

The gallery included 34 of the donated photographs in its new show “Harry Callahan at 100,” which opened Sunday. Next year is the centennial of the Detroit-born artist’s birth and his wife, Eleanor, and daughter, Barbara, made the gift.

Callahan did discuss his legacy with Gallery officials.

“It was Callahan’s hope that the National Gallery’s collection of his work would one day be one of the finest in the world and would rival its exceptional holdings of photographs by other 20th-century photographers, such as Walker Evans and Robert Frank,” said the gallery’s director Earl A. Powell III in a statement. The gallery now holds 152 photographs by Callahan.

The show is on view through March 4 in the West Building of the gallery.
