Two recent archival items offer material for analysis of Alfred Binet's (1857-1911) and Cyril Burt's (1883-1971) relationship in the early twentieth century. Burt's letter to Binet's biographer Theta Wolf was an answer to her request for information about his contact with Binet. An analysis of Burt's account prompts more questions than it answers. His statements in the letter are compared with previous ones and are put into the context of the activities of the two men, but these do not enlighten us about his actual relations with Binet. The problem arises because of Burt's desciptive vagueness and lack of supporting evidence. Despite attacks against Burt's integrity made from 1976 onward, we found no conclusive evidence of false claims. The negative outcome of this analysis probably results from Burt's faulty memory, and herein lies the caveat that personal memories make unreliable material for historical accounts.
