Director George Cukor’s 1938 movie “Holiday,” which starred Katharine Hepburn and Cary Grant, has three fictional characters based on members of the Sanford family of Amsterdam. The family founded Sanford & Sons, the first of Amsterdam’s two major carpet mills. The company merged with another firm to become Bigelow Sanford in 1929. Bigelow Sanford left Amsterdam in 1955. John Sanford inherited an estate worth $40 million when his father, Stephen Sanford, died in 1913.
