She returned to the United States at an unknown date to make a bust of President McKinley at the encouragement of then-United States Ambassador Andrew White. Cadwalader-Guild had long wanted to create a study of her fellow Ohioan. However, McKinley did not arrive to the scheduled sittings in the summer due to the campaign of 1900. She returned to Berlin and came back to the United States the following summer to meet McKinley in Canton, Ohio where he was staying. Again McKinley was too busy to pose for sittings but promised to sit for her when he returned to Washington D.C. in October. However, McKinley was assassinated in September 1901 and Cadwalader-Guild made the bust from photographs. Congress purchased the bust for $2,000. It was placed in the President's Room in the Capitol and moved to the Senate Marble Room in 2000.
