Description of the Guevara Lock of Beethoven's Hair
The lock contains hair with three clearly observable colors: grey, white, and brown. The hairs range in length from 7-15 cm. (ca. 3-6 inches). Given that hair grows at an average rate of one-half inch per month, the hair cut from Beethoven's head on his death bed represents hair grown during the last 6-12 months of Beethoven's life.
Other locks of Beethoven's hair are located in the Library of Congress, Washington, D.C.; the University of Hartford, Connecticut; the British Library, London, Great Britian; the Gesellschaft der Musikfreunde, Vienna, Austria; the Beethoven-Haus, Bonn, Germany, and some private collections.
