Hugh Ferriss (1889-1962) was an architectural renderer known for his vision of the modern city and his ability to translate vast projects into dramatic but clear-cut images. Ferriss published two books: The Metropolis of Tomorrow (1929) and Power of Buildings (1953). The collection was donated to Avery Library by Ferriss' family after his death, and has been supplemented by several later additions from other sources. 363 original drawings in the collection have been photographed and digitized and can be viewed via links in the finding aid's container listing.

Louis Henry Sullivan (1856-1924) was an American architect and partner in the Chicago architectural firm Alder & Sullivan. He is also known as a mentor to architect Frank Lloyd Wright. The core of the collection is made up of 122 drawings given to Frank Lloyd Wright by Louis Sullivan before Sullivan's death in 1924. The Avery collection represents the bulk of what remains of Sullivan's drawings. Most of the drawings in this collection are designs for ornament representing different stages of Sullivan's stylistic development. Some drawings are annotated by Wright. The collection also includes additional donations of drawings, objects, and papers collected over the years.

This collection contains professional and personal writings, published papers, correspondence, photographs, architectural records, student work, and research materials related to the academic and architectural practice of Talbot Faulkner Hamlin.
