Delano was educated at the Lawrenceville School and Yale University, where he served on the editorial board of campus humor magazine The Yale Record and was a member of Scroll and Key, and Columbia University's school of architecture. He also studied at the École des Beaux-Arts in Paris, receiving a diploma in 1903. Career He met his longstanding partner Chester Holmes Aldrich when they worked together at the office of Carrère and Hastings in the years before the turn of the 20th century. They formed their partnership after Delano's return from Europe in 1903 and almost immediately won commissions from the Rockefeller family, among others. Delano & Aldrich tended to adapt conservative Georgian and Federal architectural styles for their townhouses, churches, schools, and a spate of social clubs for the Astors, Vanderbilts, and the Whitneys. Separately (Delano was the more prolific) and in tandem they designed a number of buildings at Yale. Delano taught at Columbia University from 1903 to 1910. Delano alone won the commission for the second-largest residence in the United States, Oheka, overlooking Cold Spring Harbor on Long Island, New York for financier Otto Kahn. Built from 1914 to 1919 in French chateau style, with gardens by Olmsted Brothers, Oheka ranges over 109,000 square feet (10,000 m2) and was staffed with 125 people. In 1922, Delano designed the interiors of the Grand Central Art Galleries, an artists' cooperative established that year by John Singer Sargent, Edmund Greacen, Walter Leighton Clark, and others. Eight years later Delano and Aldrich were asked by the organization to design the U.S. Pavilion at the Venice Biennale. The purchase of the land, design, and construction was paid for by the Galleries and personally supervised by Clark. As he wrote in the 1934 catalog: Pursuing our purpose of putting American art prominently before the world, the directors a few years ago appropriated the sum of $25,000 for the erection of an exhibition building in Venice on the grounds of the International Biennial. Messrs. Delano and Aldrich generously donated the plans for this building which is constructed of Istrian marble and pink brick and more than holds its own with the twenty-five other buildings in the Park owned by the various European governments. The pavilion, owned and operated by the Galleries, opened on May 4, 1930. It was sold to the Museum of Modern Art in 1954 and later to the Guggenheim Museum. Delano's
