Thiruvaiyaru Krishnamoorthy Subramanian (aka T. K. Subramanian) passed away peacefully on August 20, 2025.  He is survived by his beloved wife, Subadra Subramanian, his brother and sister-in-law Krishnamoorthy and Chandrika Srinivasan, his children Sreekumar Subramanian and Sreelatha Subramanian Masters, his son-in-law Joseph Masters, and grandchildren Shobhini Manikarnika Kumar, Kavi Spence Masters, Sachin Ashwin-Joseph Masters and Sankalp Kumar.  

 

He lived a long and illustrious life, coming from very humble beginnings in the Tanjore district of Tamil Nadu, India.  As a student, he was particularly interested in racquet sports, including table tennis, badminton and eventually tennis.  He worked hard and excelled academically, becoming the first person in his community to graduate high school (Srinivasa Rao high school in Thiruvayaru and St. Joseph's College in Trichy) and attend college (PSG College in Coimbatore).  However, his family was so poor that he was able to attend university only after tuition, lodging and meals were written off!  

 

He married Subadra in Febrary 1965, and they lived in Bombay, India where he worked for the Bhabha Atomic Research Center (BARC).  He spent 1967-69 in Canada on a foreign deputation, and was able to travel through Europe before returning to India.  His children, Sreekumar and Sreelatha, were born in 1972 and 1976, respectively.  

 

In 1978, he decided to move to the US and began working for Bechtel in Midland, Michigan.  Over the course of the next 4 decades, the family moved to Hershey (Pennsylvania), Richland (Washington State), and Livermore (California) where he worked for, and retired from, the Department of Energy at Lawrence Livermore National Laboratories.  After retirement, he and Subadra moved to Tucson, Arizona to support their granddaughter during the time of her cancer treatmt, and then made his final move to Franklin, Tennessee so they could be closer to their grandchildren. 

 
TK lived his life according to 3 principles – 

1) Help others.
2) Do not set limits on what you can accomplish.
3) Education is to be valued.
 

He was active in volunteer efforts at religious temples, Boy Scouts of America, Toastmasters, and in math and science educational programs in the Bay Area, California.  He was tireless in motivating others to be their best.  Although we will miss him deeply, he has left an enduring legacy that will live on through all the lives he touched.
