Kerr gives Gorky's birth date in the chronology as "c. 1902". In a footnote she states that the often cited birth date of April 15, 1904 is the date that Gorky declared on his citizenship papers. She goes on to recount other conflicting reports of his birth date, including the fact that "his older sisters maintained that he was born in 1902 or 1903"; she finally concludes that "the 1902 birth date seems most plausible" (p. 366). What Kerr does not mention, however, is that the date that actually appears in the citizenship papers is not 1904 but 1903. Gorky's "Petition for Naturalization", filed in New York on January 18, 1939, as well as his earlier "Declaration of Intention", filed on May 7, 1936, both give the date of birth as April 15, 1903.
