Add another Ernest Hemingway letter to the mix that has not been previously published. The letter, written in 1926, was recently found by Jennifer Towes of the manuscripts section of the Thomas Fisher Rare Book Library. The letter shows a generous side of Hemingway who offers to go 50/50 on helping to publish writer Morley Callaghan’s novella. Both men had first met as reporters at the Star in 1923. Dr. Sandra Spanier of Penn State had confirmed that this particular letter had never been published or cited in any other Hemingway biographies.
