"After resigning his professorship of anatomy and physiology at Heidelberg due to deteriorating eyesight, Friedrich Tiedemann (1781-1861) sold his extensive personal library—over 4,600 volumes, assembled over fifty years—to Dr. Morrill Wyman (1812-1904) of Cambridge. On June 12, 1893, Wyman presented the Tiedemann Collection to the Cambridge Public Library, and Oliver Wendell Holmes said of the gift, “It is a great thing to have such a library as that of Tiedemann as a nucleus for a scientific collection. His wide investigations during his life of eighty years, through many branches of anatomy and physiology, must have caused him to bring together a great number of works of which it would be hard to find duplicates outside of the great European libraries.” After Morrill Wyman’s death, the Cambridge Public Library placed the Tiedemann collection on deposit with the Boston Medical Library in 1904; that deposit was then converted to an outright gift in 1966, following the opening of the Countway building" (https://collections.countway.harvard.edu/onview/collections/show/109).
