Dankmar Adler was a German-born American architect and civil engineer. He is best known for his fifteen-year partnership with Louis Sullivan, during which they designed influential skyscrapers that boldly addressed their steel skeleton through their exterior design: the Wainwright Building in St. Louis, Missouri (1891), the Chicago Stock Exchange Building (1894), and the Guaranty Building in Buffalo, New York (1896).

Louis Henry Sullivan was an American architect, and has been called a "father of skyscrapers" and "father of modernism." He was an influential architect of the Chicago School, a mentor to Frank Lloyd Wright, and an inspiration to the Chicago group of architects who have come to be known as the Prairie School. Along with Wright and Henry Hobson Richardson, Sullivan is one of "the recognized trinity of American architecture." The phrase "form follows function" is attributed to him, although the idea was theorised by Viollet le Duc who considered that structure and function in architecture should be the sole determinants of form. In 1944, Sullivan was the second architect to posthumously receive the AIA Gold Medal.
