I knew from the first year I was at Shell that Trilochan was one of the most able and clear thinking scientists of my generation at the Shell EPRC Laboratory and in this I was certainly correct. Later I had the pleasure to work in his Department and that was a delight. His judgment of candidates for employment was keen and extremely beneficial to Shell . . . surely as great a contribution as all his brilliant technical work.
We did not always agree but Trilochan was one of the most gentle of serious men I have ever met. But he also had a playful side. As one of the last smokers in the lab, it was to me that he came to mooch a cigarette or two at budget time after work as we prepared our case for the operating companies to review. His great delight was to construct a new way to view a technical problem and then craft a computer program to implement it and he often came by my office after normal working hours to show me his progress and bounce his displays off me . . . his form of marketing research. He always made me think harder than I had been and sometimes that was maddening but more often than not, fruitful.
Late in life, we got together for dinner now and then to discuss serious matters not related to work. He knew I would often disagree but we both enjoyed the honestly presented case for the 'other side'. I shall miss my very good and dear friend.
