In 2011, Kenneth Schwartz, then dean of the Tulane University School of Architecture, stated: "It urtis and Daviswas the pivotal firm of the city from the 1950s on. Their legacy is really extensive, not only in New Orleans but also across the world."


Founding

Nathaniel Cortlandt Curtis, Jr., and Arthur Quentin Davis formed Curtis and Davis in 1947. They knew each other as classmates at the Tulane University School of Architecture, having graduated one year apart. Curtis approached Davis about forming the firm, at a time when they perceived that the city of New Orleans was ripe for an infusion of modernist architecture. Revivalist designs had dominated New Orleans architecture in the years leading up to the founding of Curtis and Davis. In the immediate

, there was significant demand for new construction in New Orleans. For these reasons, their earliest projects were in New Orleans. In Curtis's autobiographical account of the founding of Curtis and Davis, published posthumously, Curtis stated that the founding of the firm was a "totally casual undertaking". With little thought, Davis accepted Curtis's proposal to create the firm. The two founders then capitalized the firm for USD 500 and rented office space on Union Street in the

. By 1960, the firm had a considerable number of international design projects underway and had opened satellite offices in New York, London, Berlin, and Los Angeles. It employed 40 people at its New Orleans office. Its headquarters at the time was in the Caribe Building, also a Curtis and Davis design, located at 2475 Canal Street in New Orleans.

Design style

Curtis and Davis architectural designs emphasized modernist aesthetics while making use of advances in materials and technologies. This included extensive use of the then-new technique of
lift slab construction Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of co ...
. Buildings designed by Curtis and Davis included ones for purposes that are commercial, educational, religious, recreational, residential, and even penal. The design style combined regionalism with functional characteristics in which they strived to show that the building belonged where it was built. In this respect, the firm's designs made use of courtyards, arcades, sunbreakers ( brise soleil), and cross-ventilation, all being design characteristics long used in the subtropical climate of New Orleans. Many of these same characteristics can be seen, for example, in designs of

style, bringing about an architectural flair that is characteristic of the New Orleans area. The modernist style of Curtis and Davis was at times poorly received in New Orleans where there was local pride in their historical styles of architectural design. In the early years of the firm, the local resistance to modernist style resulted in Curtis and Davis missing out on certain architectural design projects.


Representative projects

An early project of Curtis and Davis was the Municipal Court House and Precinct Jail on Rampart Street in New Orleans. The building was demolished years later. They designed the main branch of the New Orleans Public Library. The exterior has a three-dimensional aluminum screen surrounding the exterior of the two top floors of the three story building, shading the glass walls from the intense subtropical sunlight. The interior of the building has a flexible floor plan with glass interior walls. The building remains in use as a library as of 2020. In 1954, Curtis and Davis designed the Caribe Building which was to serve as the firm's headquarters. A distinctive feature of the building is the brise soleil created by Moorish-style terra cotta tiles that form a screen around much of the exterior of the building. These are situated three feet out from the building walls. In this way, workers in the building could make use of the building's windows but still be protected from the heat and glare of the sun in the oppressive subtropical climate. This design is estimated to result in a one-third savings in cooling costs of the building. In 1957, Curtis and Davis designed the Benjamin Franklin Institute which serves as the university medical center at the

. In 1964 Curtis and Davis completed its design for the Rivergate Convention Center in New Orleans. A particularly distinctive feature was the roof of the building, fabricated of pressed concrete in six barrel shapes, giving an appearance of undulation. It was a functional design in that it extended 253 feet over the main exhibit hall. In that way, the main exhibit hall was free of obstructions. The Rivergate Convention Center had 130,000 square feet of exhibit space with seating for up to 17,000 people, in addition to smaller meeting rooms. The roof design is reported to be suggestive of the flow of water in the nearby Mississippi River. The Rivergate Convention Center was demolished in 1995, as it was replaced by the larger

Following the 1965 car-bombing of the United States Embassy in Vietnam, Curtis and Davis received a commission at that time to design a new embassy for the United States, in the city then known as Saigon, South Vietnam. As the commitment of the United States to Vietnam deepened, the original design of Curtis and Davis was significantly expanded by the architectural firm Adrian Wilson and Associates. The building opened in 1967. The roof of the building subsequently was the site of the helicopter evacuation after the

Prison design

In the early 1950s, Curtis and Davis was commissioned to design the new building complex for the Louisiana State Penitentiary in Angola, Louisiana. Their design for the new facility was consistent with penal reform as advocated at the time by James V. Bennett, with facilities so that the inmates could be segregated into separate housing clusters according to their age and their security custody classification. The construction practices made use of the new lift-slab technique, as well as prison labor. The prison was completed in 1956, with construction on-time and under-budget. Among their various prison designs, Curtis and Davis served as architects for the Washington Corrections Institute in collaboration with a group of other architects, being complete in 1964. Their other prison designs included the Fox Lake Correctional Institution, in

There is a central load-bearing core and load bearing exterior walls. The building is encased in a steel lattice-work, consisting of five types of steel. The interior of the building was designed with an open, flexible floor plan. The IBM Building was a forerunner of the design for tall buildings at the time. The building remains in service and has served as the headquarters of the

Louisiana Superdome

Curtis and Davis was selected by the state of Louisiana to design the new indoor multi-purpose sports arena to be built in New Orleans, with the design being complete in 1967. Curtis and Davis intended the design of the stadium to be suggestive of the grandeur of the arenas of ancient Rome and Greece. Curtis and Davis designed the exterior of the Louisiana Superdome to have a bronze

The facility continues to host major events while other dome stadiums have become obsolete. This is cited as an example of the enduring designs that Curtis and Davis sought to achieve.


Residential projects

Curtis and Davis's residential designs were mostly mid-century modern while making use of natural settings. Fifteen of their designs were constructed in the New Orleans metropolitan area, in addition to the Harkey House of

. Curtis and Davis had designed the building with the sculpture in mind. Local people, especially parishioners at nearby Our Lady of Guadalupe Roman Catholic Church, objected to the nude art. As a result, the sculpture was removed and subsequently lost for many years. The sculpture, known as "The Family", was retrieved and became part of an Alférez collection in 2015. In 1974, Curtis and Davis allegedly donated $15,625 in political contributions in exchange for a half million dollars worth of contracts. The 1995 demolition of the Rivergate Convention Center was controversial because it was demolished in favor of construction of a new building considered architecturally inferior but resulted in construction jobs that put local politicians in a favorable light.

End of the firm

, especially Saudi Arabia. Despite several promising leads, none resulted in new construction. Early in the history of the firm, both Curtis and Davis worked together closely. As the firm expanded, they worked separately, ultimately resulting in the emergence of differing ideas between them about the firm's management. With the financial effects of economic downturn in the mid-1970s, Davis proposed selling the firm, to which Curtis agreed. The sale to Daniel, Mann, Johnson and Mendenhall resulted in the end of Curtis and Davis as a firm.


Awards and honors

Curtis and Davis won a significant number of architectural awards. Among these were several Progressive Architecture Awards, including the 1957 award for their design of the New Public Library Main Branch, for risk-taking designs that advance the practice of architecture. The firm received local, regional, and national awards from the
