large complex comprising the John F. Kennedy Library and Museum, the John F. Kennedy School of Government, and an Institute of Politics. However the project faced many delays. The MBTA would not agree to remove the heavy machinery from the land until 1970. By that time construction costs had risen to over $20 million. Only now could Pei prepare a six-month study of the site's soil, and he said the "money we had six years ago, today will barely pay for 60 percent of the original plans." Robert Kennedy, by then a senator from New York, had been serving as president of the John F. Kennedy Library Corporation until he was assassinated in 1968. Weeks before, William Manchester and Harper & Row donated $750,000 to the library. The first in a series of installments expected to total $5 million, came from the profits of the book The Death of a President which caused a bitter feud between the Kennedys and Manchester. Mrs. Kennedy remarked "I think it is so beautiful what Mr. Manchester did. I am glad that Senator Kennedy knew about it before he died." The youngest of the Kennedy brothers, Senator Edward M.

By 1971, construction had still not begun; researchers and scholars were forced to work out of the Federal Records Center which was temporarily housing some of the 15 million documents and manuscripts. Pei said there was finally "a clear way ahead"; however, he was asked to save on construction expenses by using inexpensive materials. This would translate into Pei working with concrete instead of his preferred stone. On May 22, 1971, President Lyndon B. Johnson, who succeeded Kennedy as president, saw the dedication of the Lyndon Baines Johnson Library and Museum in Austin, Texas. On the campus of the University of Texas at Austin, and next to the LBJ School of Public Affairs, he would beat the Kennedy team to building the first Presidential Library that also served as a place of scholarly research. He would not live to see work begin on his predecessor's. Meanwhile, the Cambridge community was in fierce opposition to having the library being built in Cambridge at all. Although originally welcomed in 1965, the library was now seen as a great attractor of over a million annual tourists who would change the neighborhood with
