Adler and Sullivan initially achieved fame as theater architects. While most of their theaters were in Chicago, their fame won commissions as far west as Pueblo, Colorado, and Seattle, Washington (unbuilt). The culminating project of this phase of the firm's history was the 1889 Auditorium Building in Chicago, an extraordinary mixed-use building which included not only a 3000-seat theater, but also a hotel and office building. Adler and Sullivan reserved the top floor of the tower for their own office. After 1889 the firm became known for their office buildings, particularly the 1891 Wainwright Building in St. Louis and the 1899 Carson Pirie Scott Department Store on State Street in Chicago, Louis Sullivan is considered by many to be the first architect to fully imagine and realize a rich architectural vocabulary for a revolutionary new kind of building: the steel high-rise. [edit] Sullivan and the steel high-rise Prior to the late 19th century, the weight of a multistory building had to be supported principally by the strength of its walls. The taller the building, the more strain this placed on the lower sections of the building; since there were clear engineering limits to the weight such "load-bearing" walls could sustain, large designs meant massively thick walls on the ground floors, and definite limits on the building's height. The development of cheap, versatile steel in the second half of the 19th century changed those rules. America was in the midst of rapid social and economic growth that made for great opportunities in architectural design. A much more urbanized society was forming and the society called out for new, larger buildings. The mass production of steel was the main driving force behind the ability to build skyscrapers during the mid 1880s. As seen with the data below the prices dropped significantly during this period. Price of Steel at Bessemer Steel Rails from 1867-1895 ($/ton) 1867- $166; 1870- $107; 1875- $69; 1880- $68; 1885- $29; 1890- $32; 1895- $32 The people in Midwestern America felt less social pressure to conform to the ways and styles of the architectural past. By assembling a framework of steel girders, architects and builders could suddenly create tall, slender buildings with a strong and relatively delicate steel skeleton. The rest of the building's elements — the walls, floors, ceilings, and windows — were suspended from the steel, which carried the weight. This new way of constructing buildings, so-called "column-frame" construction, pushed them up rather than out. The steel weight-bearing frame allowed not just taller buildings, but permitted much larger windows, which meant more daylight reaching interior spaces. Interior walls became thinner, which created more usable floor space. Chicago's Monadnock Building (which was not designed by Sullivan) straddles this remarkable moment of transition: the northern half of the building, finished in 1891, is of load-bearing construction, while the southern half, finished only two years later, is column- frame. (While experiments in this new technology were taking place in many cities, Chicago was the crucial laboratory. Industrial capital and civic pride drove a surge of new construction throughout the city's downtown in the wake of the 1871 fire.) The technical limits of weight-bearing masonry had always imposed formal as well as structural constraints; those constraints were suddenly gone. None of the historical precedents were any help, and this new freedom created a kind of technical and stylistic crisis. Sullivan was the first to cope with that crisis. He addressed it by embracing the changes that came with the steel frame, creating a grammar of form for the high rise (base, shaft, and pediment), simplifying the appearance of the building by breaking away from historical styles, using his own intricate flora designs, in vertical bands, to draw the eye upwards and emphasize the building's vertical form, and relating the shape of the building to its specific purpose. All this was revolutionary, appealingly honest, and commercially successful. Louis Sullivan coined the phrase "form ever follows function", which, shortened to "form follows function," would become the great battle-cry of modernist architects. This credo, which placed the demands of practical use above aesthetics, would later be taken by influential designers to imply that decorative elements, which architects call "ornament," were superfluous in modern buildings. But Sullivan himself neither thought nor designed along such dogmatic lines during the peak of his career. Indeed, while his buildings could be spare and crisp in their principal masses, he often punctuated their plain surfaces with eruptions of lush Art Nouveau and something like Celtic Revival decorations, usually cast in iron or terra cotta, and ranging from organic forms like vines and ivy, to more geometric designs, and interlace, inspired by his Irish design heritage. Terra cotta is lighter and easier to work with than stone masonry. Sullivan used it in his architecture because it had a malleability that was appropriate for his ornament. Probably the most famous example is the writhing green ironwork that covers the entrance canopies of the Carson Pirie Scott store on South State Street. These ornaments, often executed by the talented younger draftsman in Sullivan's employ, would eventually become Sullivan's trademark; to students of architecture, they are his instantly-recognizable signature. Another signature element of Sullivan's work is the massive, semi-circular arch. Sullivan employed such arches throughout his career — in shaping entrances, in framing windows, or as interior design. All of these elements can be found in Sullivan's widely-admired Guaranty Building, which he designed while partnered with Adler. Completed in 1895, this office building in Buffalo, New York was visibly divided into three "zones" of design: a plain, wide-windowed base for the ground-level shops; the main office block, with vertical ribbons of masonry rising unimpeded across nine upper floors to emphasize the building's height; and an ornamented cornice perforated by round windows at the roof level, where the building's mechanical units (like the elevator motors) were housed. The cornice crawls with Sullivan's trademark Art Nouveau vines; each ground-floor entrance is topped by a semi-circular arch. Because of Sullivan's remarkable accomplishments in design and construction at such a critical point in architectural history, he has sometimes been described as the "father" of the American skyscraper. In truth, many architects had been building skyscrapers before or contemporarily with Sullivan. Chicago itself was replete with extraordinary designers and builders in the late years of the 19th century, including Sullivan's partner Dankmar Adler, as well as Daniel Burnham, and John Wellborn Root. Root was one of the builders of the Monadnock Building (see above). That and another Root design, the Masonic Temple Tower (both in Chicago), are cited by many as the originators of skyscraper aesthetics of bearing wall and column-frame construction respectively. It may be that Sullivan's prominence in skyscraper history can be credited not only to his brilliance, but in some degree to the myth-making skills of his disciple, Frank Lloyd Wright, and to the impact of Sullivan's own book, The Autobiography of an Idea. He may also owe some of his legend to the tragic tint of his later years, which lend this great innovator's story a poignancy which has captured the imagination of student and historian alike. [edit] Later career and decline In 1890 Sullivan was one of the ten architects, five from the Eastern U.S. and five from the Western U.S., chosen to build a major structure for the "White City", the World's Columbian Exposition, held in Chicago in 1893. Sullivan's massive Transportation Building and huge arched "Golden Door" stood out as the only forward-looking design in a sea of Beaux-Arts historical copies, and the only multicolored facade in the White City. Sullivan and fair director Daniel Burnham were vocal about their displeasure with each other. Sullivan was later (1922) to claim that the fair set the course of American architecture back "for half a century from its date, if not longer."[4] His was the only building to receive extensive recognition outside America, receiving three medals from the Union Centrale des Arts Decoratifs the following year. Graceland Cemetery, Chicago, Illinois Like all American architects, Adler and Sullivan saw a precipitous decline in their practice with the onset of the Panic of 1893. According to Charles Bebb, who was working in the office at that time, Adler borrowed money to try to keep employees on the payroll.[5] By 1894, however, in the face of continuing financial distress with no relief in sight, Adler and Sullivan dissolved their partnership. The Guaranty Building was considered the last major project of the firm. By both temperament and connections, Adler had always been the one who brought in new business to the partnership, and after the rupture Sullivan received few large commissions after the Carson Pirie Scott Department Store. He went into a twenty-year-long financial and emotional decline, beset by a shortage of commissions, chronic financial problems and alcoholism. He obtained a few commissions for small-town Midwestern banks (see below), wrote books, and in 1922 appeared as a critic of Raymond Hood's winning entry for the Tribune Tower competition, a steel-frame tower dressed in Gothic stonework that Sullivan found a shameful piece of historicism. He and his former understudy Frank Lloyd Wright reconciled in time for Wright to help fund Sullivan's funeral after he died, poor and alone, in a Chicago hotel room on April 14, 1924. He left a wife and four children. A modest headstone marks his final resting spot in Graceland Cemetery in Chicago's Uptown neighborhood.
