Davis, Russell Hallet, and other partners. It was originally Brown and Hallet in 1835. Hallet & Davis was reconstituted by Davis with another Hallet (Benjamin Franklin Hallet) in Boston in the 1850s. The W. W. Kimball Company acquired Hallet & Davis in the early 1900s. In 1905, the Conway Company, a holding company, acquired the Hallet & Davis name from Kimball. In 1927, Conway disposed of its piano business. In the mid-twentieth century, the Hallet & Davis name, as well as many other U.S. piano brands, were consolidated under the Aeolian-American Corp., which declared bankruptcy in 1985.||Known as Brown and Hallet from 1835 to 1843, Hallet, Davis, & Co. is the oldest United States Piano Name still in production. Continuing the Hallet & Davis brand, and appropriate to its Boston association, there was a trademark submission in 1998 for "HALLET, DAVIS & CO. BOSTON" as was applied for by North American Music, Inc., a piano distributor. The application was "Refused/Dismissed or Invalidated" by the U.S. Patent and Trade Office (USPTO). The very next year, in 1999, North American Music applied again for a Hallet & Davis trademark, but this time simply as "HALLET, DAVIS & CO." (removing "BOSTON"), which was ultimately granted in 2001 by the USPTO. The Pearl River Piano Group of China (which manufactures HD&C pianos as well as Essex Pianos for Steinway & Sons), puts "Boston" under the HD&C and thus providing the continuity of Lineage to its roots in Boston, MA.|
