The 1855 diary was written by Charles Tracy (1810-1885), a lawyer from New York City. His daughter, Francis, who was on the trip that summer and later married J. P. Morgan, passed it to her son, Jack Morgan, who donated it to The Morgan Library in 1932. The Log Book, as it was titled, was edited by Anne Mazlish (1934-2025) and published with her notes and research in 1997. She was able to locate the 19 sketches by Frederic Church mentioned in the diary and included them in that publication. This new edition has been updated by John Bigelow Taylor, great-great-grandson of Charles Tracy.
