Sumit’s influence continues to be felt in our lives. My career and life has benefited by what Sumit did for me at a critical time. In my life. I am not alone. Many others from the Bell Labs days can confess to his very tough approach to coaching and management. Sumit taught me focus and excellence.

He continues to be missed 

Happy Birthday in heaven my dear friend 

Continue to rest in eternal peace 

Mrs Roy

I extend my hear felt Condolences on demise of Sumit which I learnt today.

I was at IIT during time Sumit was there

I have met you personally to seek advise about my Schizophrenia brother

Dr. Prakash C Kalra

• I met Sumit in Chicago area either at Dipak Roy or Bhaskar Banerjee's apartment. He was with his lovely wife Bithi.  Sumit just got his PhD from  Illinois Institute of Technology and joined the Bell Labs.  I was still a starving grad student at Northwestern.  I was told that he was the son of legendary actor Bikash Roy of the Bangla films. Of course I knew, meaning have seen numerous  movies of  Bikash Babu. Sumit was tall, somewhat serious type gentleman with a pipe hanging from his mouth. I exchanged a few words as I was more awed by his sombre personality than anything else. We have met several times. Then our path diverged. Many years later we met in northern NJ, as I was living in Berkeley Heights,  next to Mountain side where he lived.  We met several times and by then Sumit had retired from AT&T. I was dean at NJIT Business School that was quite new. As   management of information system was getting hot then, I thought that our students without  much technical background must know some technical aspects of computer technology. So I asked Sumit if he would join us.  Sumit was surprised and said that he was technical man what can he teach the business students. My reply to him that he ought explain the technology behind the information systems, so that our students will be more savvy than others. Sumit joined us and he became a very popular professor.  He developed  the e-commerce course, e-commerce was then just coming into existence.  Thus we built a closer bond. Thereafter retirement Sumit and I started to  talk about various books on phone.  During last  several years our phone Adda became a daily routine lasting for hours. Sometimes he would call or I would call. These conversations led me to discover  Sumit.  How learned he was! He had a grasp of many subjects, from literature to Indian philosophy to music. Of course I avoided discussing science with him as I repeatedly told him that was beyond me. Sumit loved Rabindranath. Once I tried  to quote a few lines, of course incorrectly. When he pointed out how I was incorrect, I shrugged it off.  He got angry and said in Bengali " no fooling with Tagore". When Covid was ramping us, he warned me and said "be care careful, if you are gone, who I will have my daily Adda". Now,  with whom will  I have my daily Adda without you, Sumit?

প্রথমে শ্রদ্ধার্ঘ্য নিবেদন করি তাঁর পুণ্য আত্মার প্রতি। চিরশান্তি লাভ করুন তিনি।

তাঁর স্মৃতিতে সৃষ্ট ওয়েব সাইট সত্যিই একটি অবদান। কিন্ত দুঃখ হল বাংলা তারিখ ব্যবহৃত হল- বাংলাদেশের জাতীয় প্রথমেই অনুসারে! পশ্চিমবঙ্গের ব্যবহৃত পঞ্জিকা  গৃহীত হল না!  বাংলা তারিখ নিয়ে বিবাদ বিসংবাদ রয়ে গেল।  সংশয় থাকলে ভারতের জাতীয় পঞ্জিকা শকাব্দ (মেঘনাদ সাহার সৃষ্ট) নিতে পারতেন।

One of my class-mates in BE College Sanat Nandy told me this story recently. He used to stay in Sengupta Hall in the college, and his and Sumit’s rooms were close to each other’s. One of the songs that Sumit liked was Aaj Jyotsna Rate Sabai Gechhe Bone. Sumit used to sing this song frequently in a loud and open voice. He sang very well. Sanat asked me to sing this song in a meeting and narrated the story.
