   Today, June 15, 2015, would have been the 100th birthday of Harry Lyman who died in 1999.  Below is a tribute written by my coach, Life Master Joel Johnson after his death.

   Joel writes:

   When I think about Harry Lyman, many descriptive identifiers come to mind,
such as

   Just seeing Harry's smiling face would always lift my spirits, as he had an infectious way of spreading warmth, comfort, happiness, to all those around him. Without Harry around, the Boylston Chess Club will never, ever be the same to me.

   Roughly twenty-five years ago, I moved to Boston. I had just dropped out of college (Math Major), and after two years of playing tournament chess, I was a low 1800-player. Over the next couple of years, I spent a considerable amount of time with Harry going over various games at the Boylston Chess Club.

   During these sessions, I was always amazed at the number of incredible ideas that would stream from his mind. No matter how dull or uneventful the position, he always seemed to find something that I would never have even considered. Many of these ideas involved some type of sacrifice or tempo gain (and many times both).

   At one session, Harry asked me about my future work, school plans. As the discussion progressed, Harry brought up the idea of going to Computer Programmer school and about there being a Technical School called Computer Learning Center where I could get the education needed to get into the field. At the time, computers were in their infancy and the only school around that I knew of with a Computer Science program was MIT. So, I checked it out and roughly 2-3 years later I returned from Los Angeles, a graduate of Computer Learning Center. I have been a Computer Programmer ever since. Thanks Harry!

   Today's society continues to struggle in the never-ending search for role models. When I look back on my life, and the various possible role models I could have chosen from (Yaz, Jim Lonborg, Rico Petrocelli, Bobby Orr, Phil Esposito, Gerry Cheevers, John Havlicek, etc.) and then, compare them to Harry, I can honestly say they couldn't have come close.

   He was a big-time chess star, one of the best players in the country during his prime. But, if you met him for the first time, you would have never known it. There was no chip on his shoulder, no arrogance, no distancing, etc. If you asked him a question, you got a straight answer. You always got the happy, cheerful Harry. Of all the wonderful traits Harry had, his ever festive and cheerful mood was the greatest of any person I have ever known, which is something that I always admired about him and what I will miss most during his absence on earth.

   Harry, may your soul Rest In Peace.
