    Carleton Monroe Winslow, Sr. was born in Damariscotta, Maine, on December 27, 1876, the son of Edwin and Clara Winslow. He studied architecture at the Art Institute of Chicago and did additional coursework at the École des Beaux Arts in Paris. He married Helen Hume in New York in 1910. They had a son, Carleton Winslow, Jr., in 1919.
    Winslow represented the New York office of Cram, Goodhue, & Ferguson as the supervising architect of the Panama-California Exposition of 1915 in San Diego. He is credited with choosing the Spanish Colonial style for the U.S. Exposition buildings, gaining favorable recognition for his work at the Exposition. In 1916, he and the Exposition's other architects co-authored a book, The Architecture and the Gardens of the San Diego Exposition: A Pictorial Survey of the Aesthetic Features of the Panama California International Exposition .
    Remaining with Bertram Grosvenor Goodhue, an architect known for synthesizing modern and traditional architectural forms, Winslow moved to Los Angeles in 1917, where he contributed to the design of the Los Angeles Public Library headquarters building, completing the work after Goodhue's death in 1924.
    A noted church architect, Winslow is best known for the Community Presbyterian Church in Beverly Hills, the First Baptist Church in Pasadena, Church of the Star of the Sea in La Jolla, and St. Mary of the Angels in Los Angeles. Winslow was a practicing Episcopalian and a trustee for the Episcopal Home for the Aged.
    After 1917, Winslow opened an additional office in Santa Barbara, where he designed Cottage Hospital and worked with Floyd E. Brewster on the Santa Barbara Museum of Natural History. Other noteworthy commissions in Santa Barbara include the Bliss, Billings, and Wilder residences.
    In 1924, Winslow worked with Edward Fisher Brown on Small House Designs, published by the Community Arts Association of Santa Barbara. Winslow became a member of the Southern Chapter of the AIA in 1916, and was became a Fellow of the AIA in 1939. He served as the president of the Los Angeles Municipal Art Commission from 1931 to 1933. He died in Los Angeles on October 16, 1946, and was survived by his wife and son.

    Scope and Content Note

    This collection contains correspondence, photographs, project files, and drawings of Carleton Winslow, Sr. The collection is comprised of personal and professional correspondence in Box 1, project files and photographs in Box 2, and oversized project drawings housed in one flat file. The collection includes correspondence from World War I, the 1920s and early 1930s, with the bulk of records dating from 1935 to 1945.
    Church project files in the collection include St. Mary of the Angels in Hollywood, one of Winslow Sr.'s better-known designs; the Episcopal Home for the Aged in Alhambra; Mission of the Holy Comforter chapel in Los Angeles; St. David's Episcopal Church of North Hollywood and St. Paul's Episcopal Church.
    The collection contains a project file as well as photographs of the Los Angeles Public Library, which Winslow and Bertram Grosvenor Goodhue began work on following the California-Pacific Exposition of 1915. Julius Shulman took the photo of the library.
    There are letters illustrated with sketches by Carleton Winslow, Sr., from his hospital bed in 1944, to his son Carleton, Jr., and letters from Carleton, Jr. to his mother and father when he was deployed in the Pacific during World War II.
    Researchers should note that when the architectural drawings and records of both Carleton Winslow, Sr. and Carleton Jr. were found in the same client file, the work by Carleton Jr. was extracted and placed in the more extensive Carleton Winslow, Jr. Collection.
    With offices in Santa Barbara as well as Los Angeles from 1917 on, Carleton Winslow, Sr. designed Cottage Hospital and residences like the Bliss House. In San Marino, he designed a Spanish style, studio residence for portrait painter Adolf Muller-Ury, for which there is correspondence in the collection. There is also a publicity list of Carleton Winslow's work, dated 1921 and 1924, and an invitation list, which includes colleagues and clients.
    Joe Weston's letters to Winslow during World War I describe aerial observer training and service in France, as well as Weston's wish to pursue a future in architecture. Weston had been employed by Winslow as an architectural draftsman before the war and would become a partner in Winslow and Weston, Associated, from 1935 to 1936. The letters and the later financial records of this partnership are also in the collection. Winslow's professional correspondence regarding National Service during World War I is in Series 2, subseries B.
    Where possible, the provenance, or original organization, of the papers has been preserved. However, in order to simplify access to the collection for researchers, some materials in specific formats and topics were reorganized and refoldered alphabetically or chronologically to reflect their contents.
