I found Jack's obituary on May 21 in an old newspaper and was so sad to hear of your loss. My husband Ron MacDonald thought highly of Jack and I remember a celebratory gathering on a few occasions with you Betsy and your dear husband. Jack had an amazing career and a lovely sense of humor and will be very much missed by his family and ours. I lost Ron March 3, 2012 How do we continue without our dear husbands? I am so sorry for your loss.

I worked at IBM in the 1960s, on several disk drives Jack Harker pioneered. This is not just silicon valley, it's also "disk drive valley" where one of the computer industry's most important products was invented, partly due to Jack's contributions.
