People whose names came up during the search for IBM 1401 information

The following names came up while I was searching for information about the IBM 1401 computer. Do you know how to contact any of them, or the heirs of those who are deceased? (I have found the guys marked with *. I have obsolete non-working addresses for the guys marked with +.) Here's a link to the San Jose IBM Retirement Club

Contact me if you have any information. I've removed my address because of all the spam I get, but you might try
