Excerpt from Oil Tanker Rates: A Life-Long Challenge It was twenty-eight years ago when I was introduced to the topic of oil transportation by Professor Adelman. I was then a student in his class when at the end of one of the sessions he said to me, You are the person I have been looking for. He went on to explain that there was a need for someone with a strong background in mathematics and management to carry forward the work of Professor Koopmans (1939) and urged that I look into it. I still remember the feelings of ambivalence that occupied me. On the one hand I was flattered by the compliment paid me by a professor I immensely respected. But at the same time, I was paralyzed by the fear of failure, for I knew thing about the subject and was fully aware of the legendary reputation of Professor Koopmans. The gentle encouragement and the confidence Professor Adelman had shown helped me overcome my fears long eugh to look into the subject. And so I immersed myself in an activity that had a profound effect on my professional orientation and is still a fascinating part of my academic life.
