sentences:  The "Memoirs" of Jeremiah Curtin were published in 1940 by the State Historical Society of Wisconsin from a manuscript presented to the society by Curtin's niece, Mrs. Walter J. Seifert, who made assurance that the material was to be credited to Curtin himself, although dictated to Mrs. Curtin, and "[s]ometimes she rewrote his matter several times".In spite of this, Professor Michal Jacek Mikos has demonstrated that the so-called "Memoirs" of Jeremiah Curtin were written not by Curtin himself but by his wife Alma Cardell Curtin from extracts from her own diaries and letters to her family.Rybicki suggests that this raises the question as to the extent of Mrs. Curtin's contribution to the various works by her husband.
