We lost another colleague this year.  In a recent internet search, Tim Hallstrom, later known as Gordon Timothy Hallstrom died in March, 2023 in Lexington, Kentucky, leaving no decendents.

Tim and I were high school friends staying in touch on and off for decades.  Sometimes not being in phone contact for many years at a time.  Strangely, I never knew much about him, what college he went to, what profession he chose or friends or partners he had.  The coroner reported he died of natural causes.
