I got back Wednesday from Washington DC where I am undergoing treatment for cancer at NIH in Bethesda. Several of the other patients know that I'm an ex-Navy Nuc and they told me there was someone I had to meet on Tuesday. This turned out to be Admiral W. J. "Bill" Cowhill, who was ComSubPac between July 1977 and May 1979 (which is before my time in service). I was only able to speak to the Admiral for a couple of minutes as the cancer treatment wing was crowded because all the Monday and Tuesday treatment appointments were being done on Tuesday because of the Federal Holiday on Monday (I'm told they ran a record number of patients through on Tuesday) and my treatment was finished in that couple of minutes (so I got unhooked so the next person could get their treatment). Admiral Cowhill apparently had a long history of working with Admiral Rickover going back to at least the 1950s when he was a Lieutenant.
Treatments at NIH are experimental in nature, so if you knew Admiral Cowhill or served under him, you might offer up a prayer for him.
