The firm's principals were leading modernists, from the 1950s to the 1970s, when International Modernism matured in America. CAN was a successor of Campbell & Aldrich, founded in 1945. Its principals were Walter E. Campbell, Nelson Wilmarth Aldrich, and Lawrence Frederick Nulty. In the late 1960s and in the 1970s, the partnership of Aldrich and Nulty designed some of New England's most recognizable and controversial modernist architecture. Building designs. Some of the New England structures designed by CAN in a modernist and frequently brutalist  idiom are Boston's 100 Federal Street 37-floor skyscraper, formerly known as the First National Bank Building and nicknamed the Pregnant Building; the Lederle Graduate Research Center at the UMass Amherst; the Merrill Science Center at Amherst College; the Weiss Science Tower at Rockefeller University; the Murdough Center at Dartmouth College; and Boston City Hall. A 1976 poll of architects, historians and critics conducted by the American Institute of Architects listed the Boston City Hall with Thomas Jefferson's University of Virginia campus and Frank Lloyd Wright's Fallingwater as one of the ten proudest achievements of American architecture  in the nation's first two hundred years. Restorations. CAN also completed renovations of some of Massachusetts' best known historical buildings, including modern annexes for some. Notable among these renovations and additions are those at Trinity Church (Boston), the only church in the United States and the only building in Boston considered by the American Institute of Architects to be one of the "Ten Most Significant Buildings in the United States"; Emmanuel Episcopal Church, Boston; and Salem, Massachusetts' John Tucker Daland House.
