The Guevara Lock of Beethoven's Hair
The Guevara Lock of Beethoven's hair was purchased at auction for £3,600 ($7,300 including commission) at Sotheby's, London, in December 1994 by four members of the American Beethoven Society: Dr. Alfredo Guevara, Mr. Ira Brilliant, Dr. Thomas Wendel, and Caroline Crummey. Mr. Brilliant, Dr. Wendel, and Mrs. Crummey then donated their portion to the Beethoven Center.
Dr. Guevara, the principal investor, donated a majority of his portion to the Center as well, and the lock is named in honor of this generous gift.
