Catalog of American Portraits

The Catalog of American Portraits (CAP), part of the National Portrait Gallery’s Office of Collections Information and Research, is a national portrait archive maintaining information and images for more than 200,000 portraits of prominent American subjects or by prominent American artists.

Results will Include National Portrait Gallery collection

What We Collect

Established in 1966, the CAP continues to acquire new material regularly and includes an ongoing survey of portraits held in collections across the country and abroad. Only one-of-a-kind likenesses are recorded, such as paintings, sculpture, drawings, miniatures, silhouettes, and daguerreotypes. Photographs, engravings, etchings, lithographs, and other graphic arts are not included, except those in the National Portrait Gallery’s collection or exhibitions.

The CAP manual files contain a photograph of the portrait, standard catalog data, current ownership, provenance, and biographical sketches of subjects and artists. Often, archival correspondence and primary research material is included as well. A costume study of dated American portraits, from the eighteenth to the mid-twentieth centuries, is also available for examination and comparison.

Images are for study purposes only, and any requests for reproductions must be directed to the owners. The CAP reserves the right to protect information provided by the cooperating owners, and information concerning private collections is restricted or kept confidential when requested. CAP personnel cannot undertake extensive research for either individuals or institutions. The staff is not permitted to provide certification of authenticity or to give appraisals. A nominal fee is charged for printing large reports and photocopying archival material.

For portrait inquiries, please tell us everything you know about the portrait in question, and include an image if at all possible. Please understand that our small staff makes it impossible to help with all requests. Our strength is in one-of-a-kind likenesses such as paintings, drawings, sculptures and daguerreotypes, preferably of identified sitters. If we are able to help, we will do our best to answer your inquiry within two weeks.
