Satyajit Sen OR Amartya Sen

Today an unforgettable incident happened during the IFM class. The faculty was discussing about the contributions of eminent personalities in the field of Finance. He went on to quote the examples of Modigliani-Miller, M. J. Gordon, Scholes, Fischer, Shapiro etc.
Now he decided to cite an Indian example. After some deliberation he could only recall 'Sen' & 'Nobel Laureate'. Even after repeated attempts he was unable to recall the first name. Finally, the poor fellow concluded that the guy is 'Satyajit Sen'. Amidst peels of laughter in the class someone sitting on the front row explained that the correct name is 'Amartya Sen'.
One friend just now mentioned that we should thank our lucky stars that he didn't say 'Aparna Sen' :-)
