Dear Lisa, Klemens forwarded your letter to me and I look forward to meeting you and Marion's other friends next Friday. Because of my deafness I won't be able to participate in conversation, but I would like to contribute in Marion's memory a file of an exchange of letters, 150 pages long, which occurred in just 34 days, nine years ago. They are accessible at http://home.earthlink.net/~ej5meyer/MN_EJM_2009_06_01.pdf Jochen
