In the summer of 1954, Phyllis Lambert was twenty-seven years old and living in Paris when she wrote her father, Samuel Bronfman, an eight-page, hand-annotated letter objecting to the design his company Seagram had approved for its new Manhattan headquarters. The letter opened with the word no, repeated five times, and it worked: Bronfman scrapped the approved design and let his daughter lead the search for a replacement. What followed was not a casual detour into architecture for Lambert but the beginning of a career. She led a roughly six-week research process, working with the architect and curator Philip Johnson to evaluate leading candidates, a process that resulted in the selection of Ludwig Mies van der Rohe. She then became the project's Director of Planning, working on the building intensively from 1954 through its completion in 1958, involved down to the design of the executive suite cabinetry, a level of engagement well beyond what a client's daughter would typically be given, and one that reflected how completely her father had handed the project over to her judgment after her initial intervention. The Seagram commission also redirected the rest of her education. She already held a BA from Vassar College, earned in 1948, but after her years on the Seagram project she went on to study at the Yale School of Architecture in 1958, then transferred to the Illinois Institute of Technology, Mies's own school, where she earned a master's degree in architecture in 1963. It is a genuinely unusual arc: a client who became, in the course of a single commission, enough of a working architectural professional to go back to school and formally train under the very architect she had helped select, closing the loop between the letter she wrote her father in 1954 and the degree she held less than a decade later.
