I didn't know Thad and Thad didn't know me.  We were aware of each other as contributors to The Liners List, an online international community of people that love Ocean Liners.  And Thad was one of us.  His insightful posts were always welcome and I'm sorry I only learned more about him after his death.  Our entire community mourns his passing.  My condolences to his family.

Dear Family of Thaddeus Constantine,
I remember Thad's smile and his passion for architecture at the BAC.  I am so saddened to learn of his passing.  His spirit will be with us.  My heartfelt condolences go to you and your family.  Warmest regards, Dean Karen Nelson

I had only brief contact with Thad just over a year ago. I discovered we were cousins of sorts while I was doing genealogy and I was able to reach out and advise that there are many Constantine family members out there. My sincerest condolences to his family, his friends, and his professional associates. May God bless and keep him.
