ms. B - footnote 2
Cornelius J. Hauck (1893-1967) was from a prominent family of Cincinnati brewers whose firm became an investment company during Prohibition in the United States. He and his wife were bibliophiles, amassing a collection that documented the history of book production worldwide. In 1966, he donated his collection to the Cincinnati Historical Society, and in the summer of 2006 the collection was sold at Christie's auction house in New York. According to the press release issued by the Cincinnati Museum Center, the collection had been built with the guidance of Emil Offenbacher, an antiquarian book-dealer based in New York. The New York sale took place on June 27-28, 2006, at Christie's Rockefeller Center.
