The bulk of the correspondence dates between 1918-1922.
Several items are undated.
The correspondence begins with a letter from Schindler asking about the possibility of a position with Wright, undated but probably November 23, 1914. It ends in August 1929 with Wright's letters of recommendation for Schindler to present to the architecture licensing board in California. Most of Wright's letters are handwritten, most of Schindler's are typed. All of Schindler's letters, except some telegrams, are carbon copies. This correspondence was part of Schindler's personal papers and was acquired by the Getty Research Institute from his son.
