About Ralph Twitchell

Lived 1890 – 1978 (aged 87). Ralph Twitchell was an American architect.

Ralph Spencer Twitchell (July 27, 1890 – January 30, 1978) was one of the founding members of the Sarasota School of Architecture. He is considered the father of the group of modernist architecture practitioners, including Paul Rudolph, Jack West, and other modernist architects active in the Sarasota area in the 1950s and 1960s like Ralph and William Zimmerman, Gene Leedy, Mark Hampton, Edward “Tim” Seibert, Victor Lundy, William Rupp, Bert Brosmith, Frank Folsom Smith, James Holiday, Joseph Farrell, and Carl Abbott. He bridged the more traditional architecture of his early work in Florida during the 1920s with his modernist designs that began in the 1940s.

Education and early career Twitchell was born to Albert John and Ella Callista (Downs) Twitchell in Mansfield, Ohio. After the untimely death of his father in 1906, his mother moved the family to Winter Park, Florida. Twitchell enrolled in Rollins College, but transferred to McGill University, Montreal, in 1910 to study architecture. In 1912, Twitchell transferred schools again, to Columbia University. After his 1917-19 World War I military service, Twitchell graduated from Columbia with a Bachelor of Arts degree in architecture in 1920 and a Masters in Architecture in 1921.

Twitchell first came to Sarasota in 1925 as the representative of New York architect Dwight James Baum to manage the final stages of the construction of John Ringling's Cà d'Zan, a Venetian-style mansion on the Sarasota Bay. Florida was in the midst of a land boom. Twitchell purchased thirteen lots in the Ravellan Gardens bayside neighborhood of Sarasota and designed Mediterranean architecture homes on these lots. Lauded in the press, the promise of the project evaporated when the Florida real estate bubble collapsed in 1926 (some surviving homes have been included on the National Register of Historic Places). Twitchell retreated to the Northeast and more favorable economic climate.

Sarasota School of Architecture In 1936, Twitchell moved permanently to Sarasota to open his own architectural and construction company, Associated Builders. Among his earliest commissions were a Siesta Key residence for author MacKinlay Kantor and the Lido Beach Casino. In the following years, Twitchell (influenced by the innovative architecture of Frank Lloyd Wright and LeCorbusier) began experimenting with reinforced concrete and glass structures, facilitating a more modernist approach.

In 1938, the American Institute of Architects revoked Twitchell's membership, primarily due to Twitchell's ownership of a construction company. At that time, the profession took a dim view of architects engaged in construction. Twitchell believed, however, that the Florida landscape required a unique understanding of building site planning that could be only be accomplished by merging design and construction. The revocation had no bearing on his ability to work. In 1976, two years before his death, the AIA reversed its decision and recognized Twitchell for his career achievements by naming him "Architect Emeritus."

Rudolph returned to Twitchell's Siesta Key office in 1946 and partnered with him until 1951. Rudolph focused on the idea of the structure while Twitchell prioritized construction details. Typically, each project required three or four iterations, expressed sequentially, until the initial creative concept became rooted to the specifics of its site. (Cocoon House 1950), and the Leavengood Residence in St. Petersburg, Florida (1951). The Revere Quality House, with rooms that opened out onto terraces and landscaped areas, was the first poured concrete house on Siesta Key. Such open design was reflective of the Sarasota School of Architecture philosophy: clarity of construction, maximum economy of means, clear geometry, and honesty in details.

Twitchell and Rudolph parted ways in 1951. Between 1953 and 1954, Twitchell partnered with another "Sarasota School" architect, Jack West, and between 1959 and 1965 with his son, Tollyn Jules Twitchell. Ralph Twitchell died in Sarasota, Florida, on January 30, 1978.

Personal life Twitchell married three times and had five children: Sylva, Tollyn and Terry from his first marriage, and Aaron and Debbie from his second marriage.
